Introduction

3 November 2023: Read the NZCA's submission on 'Helping nature and people thrive – Exploring a biodiversity credit system for Aotearoa New Zealand'.

The Legislative Basis for the New Zealand Conservation
Authority (NZCA) submission

  1. The New Zealand Conservation Authority / Te Pou Atawhai Taiao o Aotearoa (Authority, NZCA) was established under the Conservation Act 1987 (Act), with members appointed by the Minister of Conservation. It is an independent statutory body with a range of functions, but primarily acts as an independent conservation advisor to the Minister and the Director-General of Conservation.
  2. The Authority has a role as an objective advocate on matters of national significance
    and interest in the conservation arena and to provide high quality independent advice
    to the Department of Conservation (Department, DOC) on its strategic direction and
    performance.
  3. The Authority has a range of powers and functions, under the Act, as well as under
    other conservation related legislation. Section 6C(2)(c) of the Act provides the
    Authority with the power to “advocate the interests of the Authority at any public forum
    or in any statutory planning process.”
  4. Following the logic of the above powers and functions, and the fact that the
    implementation of the Aotearoa New Zealand Biodiversity Strategy is a strategic
    priority for the Authority, the Authority submits their views on the proposed Biodiversity
    Credit System.

NZCA submission

  1. The NZCA submission is based on its analysis of:
     • Te āwhina i te taiao me ngā tāngata kia puāwai
    Helping People and Nature Thrive: Exploring a biodiversity credit system for
    Aotearoa New Zealand.
  2. In this submission, the Authority first sets out its key submission points, then responds to the Discussion Document questions.

Key submission points 

  1. The Discussion Document states that
    Biodiversity credit systems (BCSs) are described in the Discussion Document as an
    increasingly popular way of using private sector funding to support landholder and
    central and local government efforts to protect, maintain and enhance biodiversity.
    … By purchasing credits, people and organisations can finance and claim recognition
    for actions and outcomes related to protecting and enhancing nature on public and
    private land, including whenua Māori.
  2. The Authority supports in principle the establishment of a system that provides a
    consistent methodology for allocating credit to investments in biodiversity, and for
    measurement and verification of claimed biodiversity gains. It supports the
    establishment of a BCS, subject to management of the risks discussed in the
    Discussion Document and in this submission.
  3. The Authority supports a BCS that:
    a. Incentivises activities that benefit biodiversity, ideally with co-benefits for climate
    mitigation and adaptation.
    b. Supports te ao Māori (including the exercise of kaitiakitanga) and mātauranga
    Māori, and gives effect to te Tiriti o Waitangi.
    c. Fosters involvement in community conservation projects
  4. Implementation of Te Mana o Te Taiao - The Aotearoa New Zealand Biodiversity
    Strategy (“Biodiversity Strategy”) is a strategic priority for the Authority. The Discussion
    Document references the Biodiversity Strategy only in a very general sense (that a
    BCS could support implementation of the Biodiversity Strategy), and the only other
    references are where “state of the environment” information contained in the
    Biodiversity Strategy is relied upon. Further analysis of how a BCS can be designed in
    a manner that specifically assists achievement of the Biodiversity Strategy’s stated
    goals and outcomes is needed
  5. The Authority commends the Ministry for its broad analysis of BCSs (and similar
    systems) across the world, in formulating the proposals in the Discussion Document.
    Careful analysis of how those other systems provide for New Zealand’s unique
    features, including a high degree of endemism, extreme levels of existing biodiversity
    and habitat loss, and the high cultural value placed on taonga species, will be required.
  6. The Authority sees two high level risks from the formal implementation of a BCS in
    New Zealand:
    a. The first risk is that over time, the BCS comes to be seen as a replacement for
    proper regulation of activities that result in loss of biodiversity.
    • A BCS cannot replace adequate regulation of activities that would result in
    loss of biodiversity. The indigenous flora and fauna of Aotearoa is already
    significantly depleted. Most remaining ecosystems have features that
    mean if they are depleted or destroyed, they cannot simply be replaced by
    new plantings, or protection of other ecosystems. As a result, it is essential
    that any BCS sits alongside a National Policy Statement on Indigenous Biodiversity (“NPSIB”) containing objectives, policies and methods designed to protect significant natural areas and maintain indigenous
    biodiversity across Aotearoa, and regional and district rules that implement
    the NPSIB.1
    • Put another way, a BCS risks prioritisation of “trading” of positive for
    adverse biodiversity impacts over other measures such as avoidance and
    remediation, which are inherent in the “mitigation hierarchy”. As discussed,
    in Maron et al (2023):2
    If nature positive is translated into action with rigour, the wide global appeal
    of the concept presents an opportunity to trigger smarter avoidance and
    more-effective mitigation of impacts, as well as to incentivize long-term, fair
    and equitable outcomes for nature and people from ecological restoration
    and rewilding investments. However, if it replaces established, rigorous
    approaches such as the mitigation hierarchy, it risks amounting to mere
    greenwash. Embedding the mitigation hierarchy as an essential, but not
    sufficient, condition is the first step in the journey to nature positive. …
    Nature positive should not be used as cover for accumulation of further
    losses for biodiversity features that are already threatened.
    • Despite the evidence that voluntary methods alone are not effective at
    protecting indigenous biodiversity, regulation of activities that impact
    biodiversity is controversial, and political gains can be made by promises to
    “remove red tape” or “abolish SNAs”. The existence of a BCS carries the
    risk of supporting calls to weaken environmental regulation by appearing to
    provide an alternative voluntary system of biodiversity protection. If that
    eventuates, the BCS will have achieved the opposite of what is intended.
    The Authority submits that the principle that “the BCS complements, and does not
    replace, regulation of activities that result in biodiversity loss” should be enshrined in
    the BCS, to minimise the risk described above.
    b. The second risk comes from the inappropriate use of biodiversity credits as
    “offsets” or “compensation” to address the effects of activities that damage
    biodiversity:
    • The Discussion Document says that whether credits are used as an offset
    or not could be a design choice for a BCS.
    • The NPSIB and the Natural and Built Environment Act 2023 (“NBE Act”)
    provide for effects on biodiversity to be “offset,” provided (for most
    activities) there have been attempts to avoid, remedy or minimise effects
    first. If offsetting is not possible, effects can be “compensated for”.
    • Credits are more likely to equate to compensation than offsets, as they are
    unlikely to meet the requirements for offsets, in particular that an offset
    action must be “like for like”.
    • The Authority has concerns about the existing approach to offsetting and
    compensation in the NPSIB and NBE Act, as they allow for biodiversity
    loss. Allowing biodiversity credits to be used for offsets will incentivise the
    use of offsets and compensation, when these tools should be a last resort for activities with significant public benefits that cannot proceed in any
    other way.
    • Allowing biodiversity credits to be used for offsets or compensation implies
    that a positive “benefit” has been achieved, yet the “benefit” has only
    happened in response to the adverse effect. So, there is only a neutralising
    (at best) of a biodiversity loss rather than a “benefit” to biodiversity. While
    the Discussion Document says that credits used for offsetting could not be
    used to make nature-positive claims, a positive outcome is inherent in the
    concept of a “credit”, and so the underlying purpose of the BCS becomes
    confused.
    • The use of BCS credits for offsetting turns the BCS into a biobank for
    sourcing offset credits. The risks of this are described in Maseyk et al
    (2022):3
    New Zealand is still grappling with many of the fundamentals of biodiversity
    offsetting. It is premature for councils to pursue formal schemes to deliver
    biodiversity offsets or compensation while key institutional settings
    (including knowledge, capacity, governance, and compliance) are still
    lacking. Until these issues are resolved, formal strategic mechanisms,
    including biobanking, should not be pursued by councils, as doing so risks
    entrenching further biodiversity declines. The premature establishment of
    formalised strategic mechanisms will not improve on the status quo and
    may serve to entrench poor practice.
    Formalised market-based schemes would necessitate a simplification of
    exchange to facilitate the trade, thus ‘relaxing’ offset design principles
    (e.g., degree of ecological equivalence or spatial proximity of the gains to
    the losses), and rigour and are therefore more likely to lend themselves to
    compensation outcomes. Facilitating compensation trades over biodiversity
    offsetting to a no net loss or net gain standard is not an appropriate
    response to the biodiversity or climate crises.                                                                                    The Authority submits that a BCS should not be used to provide credits to “offset” or “compensate for” activities resulting in biodiversity loss.
  7. The Discussion Document focusses on how a BCS would work on land. More work is
    required to design a BCS suitable for freshwater and marine ecosystems.
  8. The Authority agrees that the principles of BCS design and implementation are critical.
    A further round of consultation on these is necessary should Government proceed with
    a BCS.
  9. The Discussion Document recognises the importance of the “Role of Experts”,
    although this title is misleading as the discussion is really about the importance of
    building a skilled workforce rather than “experts”. The Authority strongly agrees that
    capacity and capability building is essential. The Discussion Document says that a
    scheme such as Mahi mō te Taiao – Jobs for Nature that creates nature-based
    projects, could support a BCS. The Authority agrees, but understands that Mahi mō te
    Taiao is coming to an end in June 2025.4 The Authority would support reinvigoration of Mahi mō te Taiao, with appropriate funding. This will require additional funding for the
    Department of Conservation, if capacity building is to come from its budget.

Authority Responses to Discussion Document Questions

  1. Do you support the need for a biodiversity credit system (BCS) for New Zealand?
    Please give your reasons.
    • The Authority supports in principle a BCS, subject to ensuring the risks identified
    in this submission and in the Discussion Document are fully addressed so that
    there is confidence that a BCS will in practice contribute to maintaining and
    enhancing biodiversity.
  2. Below are two options for using biodiversity credits. Which do you agree with?
    (a) Credits should only be used to recognise positive actions to support biodiversity.
    (b) Credits should be used to recognise positive action to support biodiversity, and
    actions that avoid future decreases in biodiversity. Please answer (a) or (b) and
    give your reasons.
    • Credits should only be used to recognise positive actions to support biodiversity
    as described in (a).
    • “Averted loss” actions, as described in (b), assume that activities that result in
    loss of biodiversity will be allowed so there is a “benefit” in averting the loss. In a
    system with adequate environmental regulation, all activities should be
    undertaken to at least achieve no net loss. That is the objective of the NPSIB.5
    In that context, there is no benefit in averting a future loss, as those losses must
    be averted anyway. Additionally, the gains from “averted loss” actions are very
    difficult to estimate (see Maseyk et al (2023)6).
    • For clarity, avoiding future decreases in biodiversity due to non-human impacts
    (e.g. pest control that manages current and future populations of browsing
    animals) is part of option (a) and should be encouraged as part of a BCS.
  3. Which scope do you prefer for a biodiversity credit system?
    (a) Focus on terrestrial (land) environments.
    (b) Extend from (a) to freshwater and estuaries (e.g., wetland, estuarine restoration).
    (c) Extend from (a) and (b) to coastal marine environments (e.g., seagrass
    restoration).
    Please answer (a) or (b) or (c) and give your reasons.
    • The Authority supports a BCS that applies to all domains (Option C). A vast
    proportion of New Zealand’s biodiversity is found in marine environments yet is
    often overlooked.
    • However, significant further work is required to design a BCS suitable for
    freshwater and marine ecosystems. For marine ecosystems in particular, fishing
    is one of the main impacts on biodiversity. The BCS would need to take into
    account what activities are already permitted under the Fisheries Act 1986 to
    ensure that purported biodiversity gains are not undermined by legal fishing. A
    BCS could provide encouragement for iwi and hapū to protect their rohe moana (and receive a benefit for their work in doing so) using existing tools under the
    Fisheries Act and RMA.
  4. Which scope do you prefer for land-based biodiversity credits?
    (a) Cover all land types, including both public and private land including whenua Māori.
    (b) Be limited to certain categories of land, for example, private land (including whenua
    Māori).
    Please answer (a) or (b) and give your reasons.
    • The Authority does not support application of a BCS to land managed under the
    Conservation Act and legislation referenced in Schedule 1 of the Conservation
    Act. Such land is already subject to a requirement that it be protected, preserved
    or similar (depending on its status).
    • The Authority supports the ability for Māori to generate BCS credits for activities
    that protect biodiversity on whenua Māori.
  5. Which approach do you prefer for a biodiversity credit system?
    (a) Based primarily on outcome.
    (b) Based primarily on activities.
    (c) Based primarily on projects. Please answer approach (a) or (b) or (c) and give your
    reasons.
    • The Authority acknowledges that there are pros and cons with each option. A
    projects-based approach is likely to provide the most benefit for groups and
    individuals undertaking conservation projects as it will likely have the lowest
    transaction costs (such as requirements for assessment of specific biodiversity
    gains). However, an outcome-based approach is likely to be most robust in
    ensuring the biodiversity gains inherent in a biodiversity credit are actually
    achieved. At this stage, the Authority does not have an opinion on which
    approach is best.
  6. Should there also be a requirement for the project or activity to apply for a specified
    period to generate credits? Please answer Yes/No and give your reasons.
    • Yes, and this is inherent in the “permanent or long-term” BCS principle. Short-term projects or activities are unlikely to achieve lasting biodiversity gains.
  7. Should biodiversity credits be awarded for increasing legal protection of areas of
    indigenous biodiversity (e.g., QEII National Trust Act 1977 covenants, Conservation
    Act 1987 covenants or Ngā Whenua Rāhui kawenata? Please answer Yes/No and
    give your reasons.
    • No. Increasing legal protection does not achieve biodiversity gains, unless it is
    accompanied by permanent or long-term actions such as fencing, pest control, or
    planting. The credit should relate to the biodiversity outcome not the change in
    legal status.
    • See also the Authority’s response to question 4 in relation to conservation land.
  8. Should biodiversity credits be able to be used to offset development impacts as part of
    resource management processes, provided they meet the requirements of both the
    BCS system and regulatory requirements?
    • No. See paragraph 7(b) of the Authority’s key submission points.
  9. Do you think a biodiversity credit system will attract investment to support indigenous
    biodiversity in New Zealand? Please give your reasons.
    • No opinion
  10. What do you consider the most important outcomes a New Zealand biodiversity credit
    system should aim for?
    • The most important outcome for a BCS is that it assists in halting biodiversity
    decline. Important co-benefits are: mitigating and adapting to climate change,
    enhancement of freshwater quality and aquatic habitats, engaging people in
    conservation in ways that increases their connection to nature, enhancing the
    mana of taonga species and ecosystems.
  11. What are the main activities or outcomes that a biodiversity credit system for New
    Zealand should support?
    • The main activities or outcomes that a BCS should support are those that involve
    active interventions that can be demonstrated to enhance biodiversity, such as
    planting, pest control, habitat enhancements that remove sediment or nutrient
    run-off. Ideally, activities or outcomes would also provide for (and these are
    related/overlapping concepts): the exercise of kaitiakitanga by Māori, community
    conservation projects, projects that build capacity.
  12. Of the following principles, which do you consider should be the top four to underpin a
    New Zealand biodiversity credit system?
    Principle 1 – Permanent or long-term (e.g., 25-year) impact
    Principle 2 – Transparent and verifiable claims
    Principle 3 – Robust, with measures to prevent abuse of the system
    Principle 4 – Reward nature-positive additional activities
    Principle 5 – Complement domestic and international action
    Principle 6 – No double-counting, and clear rules about the claims that investors can
    make
    Principle 7 – Maximise positive impact on biodiversity
    • It would be clearer if there were two sets of principles, one set for principles that
    relate to the action that generates the credit (additionality, permanent or long-term impact, biodiversity outcome, alignment with regional/domestic/international
    outcomes) and a second set of principles that relate to the design of the scheme
    (transparent and verifiable, robust, no double counting, clear rules for investors)
    • All of the proposed principles are important and should be retained. However,
    there appear to be overlaps, e.g. Principle 4 (“additional activities”) and Principle
    6 (“no double counting”), and Principle 2 (“verifiable claims”) and Principle 6
    (clear rules about the claims investors can make”) so it should be possible to
    reduce these to 4 principles without losing any components.
    • The NPSIB provides for regional councils to prepare regional biodiversity
    strategies and to have regard to these when developing restoration objectives,
    policies, and methods for inclusion in regional policy statements and plans.7 The purpose of a regional biodiversity strategy is to promote the landscape-scale
    restoration of the region’s indigenous biodiversity. A regional biodiversity
    strategy must meet the requirements of Appendix 5 of the NPSIB. This includes
    supporting achievement of domestic targets, and enables measures that are intended to implement other objectives, such as biosecurity, climate mitigation,
    amenity, or freshwater outcomes, where those measures also contribute to
    protection and restoration of indigenous biodiversity. It makes sense, given the
    work that will go into regional restoration planning through this mechanism
    (including public and Māori consultation and input) and given that Appendix 5
    already contains many similar requirements or goals to those that a BCS would
    be aiming for, that there should be good alignment between actions that produce
    biodiversity credits and regional biodiversity strategies. Accordingly, Principle 6
    should be amended to focus on “Consistent with regional biodiversity strategy”,
    with domestic and international action having a secondary focus if they are
    referenced at all. Alignment with international action may be complex to achieve
    (or demonstrate) in practice. 
  13. Have we missed any other important principles?
    Please list and provide your reasons.
    • There are no principles relating to the cultural importance of species and
    ecosystems, the exercise of kaitiakitanga by Māori, and protection of taonga
    species. This is a significant omission. While not every action that generates a
    biodiversity credit needs to actively achieve cultural benefits, all actions should at
    least consider how cultural benefits can be achieved, how the exercise of
    kaitiakitanga can be supported, and how matauranga Māori can be incorporated.
    • An additional principle should be included, stating that “the BCS complements,
    and does not replace, regulation of activities that result in biodiversity loss”
    should be enshrined in the BCS, to minimise the risk described in paragraph 12
    of the Authority’s key submission points.
    • See also the Authority’s response to Q12 regarding consistency with the relevant
    regional biodiversity strategy.
  14. What assurance would you need to participate in a market, either as a landholder
    looking after biodiversity or as a potential purchaser of a biodiversity credit?
    • N/A
  15. What do you see as the benefits and risks for a biodiversity credit market not being
    regulated at all?
    • If one or more non-regulated BCSs establish on a large scale, there is potential
    for these not to produce the biodiversity gains they claim. While this is not a risk
    in and of itself, the main resulting risk is the diversion of investment away from
    projects that are achieving better biodiversity gains. The main benefit of a non-regulated BCS is the low or nil transaction cost to public funds.
  16. A biodiversity credit system has six necessary components (see figure 5). These are:
    project provision, quantification of activities or outcomes, monitoring measurement and
    reporting, verification of claims, operation of the market and registry, investing in
    credits. To have the most impact in attracting people to the market, which
    component(s) should the Government be involved in? Please give your reasons.
    • The main component that the Government should be involved in is operation of
    the market and registry. Quantification of outcomes, monitoring, measurement
    and reporting, and verification of claims are also important but should be able to
    be undertaken by private entities provided appropriate rules are established
    (potentially with the Government having an audit role).
    • Ideally, Government would also to have an indirect role in project provision, by
    funding projects through schemes such as Mahi mō te Taiao - Jobs for Nature.
  17. In which areas of a biodiversity credit system would government involvement be most
    likely to stifle a market?
    • Government should provide principles that projects must achieve to qualify to
    earn BCS credits, but Government should not specify which projects will or will
    not achieve credits, as this is likely to discourage innovation.
  18. Should the Government play a role in focusing market investment towards particular
    activities and outcomes and if so why? For example, highlighting geographic areas,
    ecosystems, species most at threat and in need of protection, significant natural areas,
    certain categories of land.
    • Yes, but this should occur through regional biodiversity strategies as already
    provided for in the NPSIB.
  19. On a scale of 1, not relevant, to 5, being critical, should a New Zealand biodiversity
    credit system seek to align with international systems and frameworks? Please give
    your reasons.
    • 2 – somewhat relevant. Alignment with international systems and frameworks is
    not necessary for a New Zealand BCS to contribute to halting the decline of New
    Zealand biodiversity, so at least initially this should not be a priority. Alignment
    may assist in attracting overseas investment in New Zealand projects so could
    be something that is considered if a New Zealand BCS is established and proves
    itself.
  20. Should the Government work with private sector providers to pilot biodiversity credit
    system(s) in different regions, to test the concept? If you support this work, which
    regions and providers do you suggest?
    • Yes, “on the ground” pilots tend to be useful. The Authority has no opinion on
    which regions should be prioritised for this.
  21. What is your preference for how a biodiversity credit system should work alongside the
    New Zealand Emissions Trading Scheme or voluntary carbon markets?
    (a) Little/no interaction: biodiversity credit system focuses purely on biodiversity, and
    carbon storage benefits are a bonus.
    (b) Some interaction: biodiversity credits should be recognised alongside carbon
    benefits on the same land, via both systems, where appropriate.
    (c) High interaction: rigid biodiversity ‘standards’ are set for nature-generated carbon
    credits and built into carbon markets, so that investors can have confidence in
    ‘biodiversity positive’ carbon credits.
    Please answer (a) or (b) or (c) and give your reasons.
    • The Authority’s view is that projects that only achieve a biodiversity outcome, or
    only achieve a carbon storage benefit, should still be recognised under each
    system, with projects achieving co-benefits being encouraged. If there are to be
    nature-generated carbon credits within carbon markets that are described as
    “biodiversity positive”, then it is important that these meet principles that ensure
    they are actually generating biodiversity gains.
    • It is not clear to the Authority how each system (level of interaction) would affect
    the proposed BCS or the ETS, or that options a, b and c are the only options - so
    the Authority is not in a position to choose between option a, b or c.
  22. Should a biodiversity credit system complement the resource management system?
    (Yes/No) For example, it could prioritise:
    Significant Natural Areas and their connectivity identified through resource
    management processes,
    endangered and at-risk taonga species identified through resource management
    processes.
    • Yes, a BCS should complement the resource management system, by
    complementing implementation of the restoration-focussed aspects of the
    NPSIB. This is achieved by referencing regional biodiversity strategies in the
    BCS principles.
  23. Should a biodiversity credit system support land-use reform? (Yes/No) (For example,
    supporting the return of erosion-prone land to permanent native forest, or naturebased solutions for resilient land use.)
    • Yes, and this appears inherent in the principles proposed elsewhere in the
    Discussion Document (permanent or long-term impact, maximised biodiversity
    impact).

  1. It is also essential that national policy and regulation is expanded to also address marine biodiversity (the NPSIB presently
    only addresses terrestrial biodiversity)
