Seismic surveys use loud sound to search for features, such as oil and gas, under the sea floor. These sounds have the potential to impact marine mammals in various ways.
Code of Conduct developed in 2012
In 2012 DOC developed a voluntary Code of Conduct for Minimising Acoustic Disturbance to Marine Mammals from Seismic Survey Operations (the Code) following discussions with international and domestic stakeholders representing industry, observers and marine scientists.
The Code and the supporting reference document aim to provide effective, practical mitigation measures for minimising acoustic disturbance of marine mammals during seismic surveys.
The Code has been endorsed as industry best practice by the Petroleum Exploration and Production Association of New Zealand (PEPANZ).

Exclusive Economic Zone regulations
Under the Exclusive Economic Zone and Continental Shelf (Environmental Effects – Permitted Activities) Regulations 2013, seismic surveying is a permitted activity within EEZ waters provided the Code is complied with. The Environmental Protection Authority (EPA) is responsible for monitoring seismic surveys within the EEZ to determine compliance with the Code.
The Code was updated slightly at this time to facilitate this.
See the EPA website for more details.
Reviewing the Code of Conduct
At the time it was implemented, DOC committed to a review of the Code after three years.
Accordingly, the 2013 Code is currently undergoing a thorough review. This process is again drawing on the expertise of a diverse array of specialists and stakeholders to provide DOC with the information required to improve the Code for current and future survey technologies.
Feedback was solicited from these experts in July, 2015. Since then, a series of Technical Working Groups have been working to improve several key areas of the Code in response to that feedback.
Also, DOC is exploring ways to have a more outcome-focused approach to facilitate the use of new technologies under the Code. This was suggested by several stakeholders, including industry.
A separate regulatory process will be needed to implement the new code when it is finalised. Meanwhile, the 2013 Code will remain in force.
