Marine protected areas research
DOC’s research helps make sure marine protected areas (MPAs) cover the right places and are managed effectively to create a comprehensive network to protect Aotearoa marine biodiversity.

Marine protected areas design, review and guidance

Tools and guidance to help the design of a network of well-connected MPAs in New Zealand that represents all types of marine environments.

New Zealand Marine Protected Areas: Principles for network design

Published: 2019

This paper provides an overview of the fundamental principles of designing an effective network of marine protected areas, including representation, replication, adequacy, viability and connectivity.

A review of the objectives of New Zealand's marine reserves

Published: 2020

This report:

  • summarises the objectives for the 44 marine reserves established in NZ to date
  • reviews what objectives may need to be considered in potential future marine protection.

A review of habitat use, home range, and connectivity for New Zealand species

Published: 2020

This report examines habitat use, home range size, dispersal, and connectivity patterns for certain New Zealand marine species. It discusses the need to take species-specific requirements into account when planning and establishing marine protected areas.

Guidance for the use of decision-support tools for identifying optimal areas for biodiversity conservation

Published: 2020

This report outlines how to use predictive species distribution models, point records, and polygon datasets in Zonation for spatial conservation prioritisation, including how to address data uncertainty and overlap.

Evaluating the effectiveness of marine protected areas in New Zealand: Theme 1 - Design element

Published 2021

This report presents a methodology for evaluating the effectiveness of MPAs and MPA networks using the design principals of :

  • viability
  • adequacy
  • representativity
  • replication
  • ecological connectivity
  • areas of importance 
  • integration with other spatial management measures.

Evaluating representativity of marine spatial management areas using the New Zealand Seafloor Community Classification

Published 2025

This paper presents an evaluation of the representativity of benthic communities within current spatial management areas across New Zealand's marine environment. The evaluation is based on a novel approach that uses the extent of each New Zealand Seafloor Community Classification (NZSCC) group within spatial management areas, estimates of within‐ and between‐group similarities and taxonomic richness.

Achieving full representativity of seafloor biodiversity with minimal expansion: exploring a strategy for New Zealand marine conservation

Published 2026

This paper uses the New Zealand Seafloor Community Classification (NZSCC) and the conservation planning software Zonation to explore how representativity of benthic communities could be enhanced across spatial management areas (including protected areas) in New Zealand’s marine environment.

Ecosystem responses to marine protection

How marine protection influences ecosystem structure, function, and resilience, with a focus on biodiversity and habitat integrity.

Communicating the value of marine conservation using an ecosystem service matrix approach

Published 2019

This paper presents a matrix method for evaluating Ecosystem Service Potential (ESP) in New Zealand's benthic marine habitats. This method can be used to identify and monitor the non-market benefits of supporting and regulating services in current or proposed MPAs.
