The Decision

Decision on the TTR marine consent application

The Decision-making Committee appointed by the EPA Board to decide on the application by Trans-Tasman Resources Ltd for a marine consent has delivered its decision.

In summary, Trans-Tasman Resources Ltd (TTR) sought a marine consent under the Exclusive Economic Zone and Continental Shelf (Environmental Effects) Act 2012 ( the EEZ Act) to undertake iron ore extraction and processing operations. The application area was 65.76 square kilometres, located between 22 and 36 kilometres (12 and 19 nautical miles) offshore in the South Taranaki Bight.

The Decision-making Committee (DMC) appointed by the Environmental Protection Authority to hear and determine the marine consent application, has REFUSED consent. 

The DMC has issued a comprehensive decision setting out its reasons for refusing the consent.  The major reasons for this were the uncertainties in the scope and significance of the potential adverse environmental effects and those on existing interests (such as the Fishing Interests and Iwi). The applicant and most submitters acknowledged that there was uncertainty and that in these circumstance the EEZ Act requires the EPA to favour caution and environmental protection (sections 61(2) of the EEZ Act).  With respect to uncertainty, the DMC considered whether the adaptive management approach proposed by the applicant would enable the application to be undertaken (sections 61(3) of the EEZ Act).  The DMC found that the conditions proposed by the applicant (including the adaptive management approach) were not sufficiently certain or robust for the application to be approved given the uncertainty and inadequacy of the information presented about the potential adverse effects.  The DMC also considered that there was also a lack of clarity about the extent of economic benefit to New Zealand outside of royalties and taxes and the economic value of the adverse effects.

Overall the DMC found that the application did not meet the sustainable management purpose of EEZ Act, including that it was not satisfied that the life-supporting capacity of the environment would be safeguarded or that the adverse effects of the proposal could be avoided, remedied or mitigated, given the uncertainty and inadequacy of the information presented.
