Threat Management Plan Review for Maui’s dolphin

Submissions closed Monday 12 November 2012

Feedback was requested on a range of options and recommendations for mitigating both fishing and non-fishing human induced threats to Maui’s dolphins.

Purpose

This consultation supports a review and update of the Maui’s dolphin portion of the Hector’s and Maui’s Dolphin Threat Management Plan.

The previous Threat Management Plan was undertaken 5 years ago in 2007. This review process aims to reassess management measures based on:

  • updated information on the Maui’s dolphin population
  • the human-induced threats they are exposed to, and
  • their vulnerability to those threats.

The Department of Conservation (DOC) and the Ministry for Primary Industries (MPI) are seeking feedback from whanau, hapu, iwi, stakeholders and the public.

This is the current information available about threats to Maui’s dolphins and was presented to the expert panel at the Maui’s dolphin risk assessment workshop held in June 2012. The results of the workshop informed the development of the options for Maui's dolphin, which we are now seeking your feedback on.

About Maui's dolphins

Maui's dolphins, a subspecies of Hector’s dolphins, are endemic to New Zealand, meaning they are only found in New Zealand's waters.

A recent abundance estimate for Maui's dolphin for 2010-11, indicates as few as 55 individuals over one year of age remain (95% confidence interval of 48 - 69). (See Abundance estimate).

The DOC New Zealand Threat Classification System ranks Maui's dolphin as "nationally critical" the highest ranking category.

Maui’s dolphin is also classified according to the IUCN Red List Categories and Criteria. Under the criteria, Maui's dolphin is classified as "critically endangered", such that the best available evidence indicates that this subspecies is considered to be facing an extremely high risk of extinction in the wild.

Why review the Threat Management Plan?

Public and government concern over the effect of human induced mortality on Maui's dolphin, the recent abundance estimate and an incidental capture of a Maui’s or a Hector’s dolphin off of Cape Egmont in January has led to a review of the Maui’s component of the Hector’s and Maui’s dolphin Threat Management Plan. The review of the Hector’s component will be undertaken in 2013.

DOC and MPI are reviewing the Maui’s dolphin component of the Hector’s and Maui’s dolphin Threat Management Plan. The plan seeks to:

  • describe the nature and extent of threats to Hector's and Maui's dolphins, and
  • implement strategies to reduce those threats which are human induced.

This revised version builds on the previous Threat Management Plan consulted on in 2007.
