Māui dolphins (Cephalorhynchus hectori maui), a sub-species of New Zealand’s endemic Hector’s dolphin (C. hectori), are critically endangered. Numbering 63 individuals (95% CI: 57–75) over 1 one year of age, Māui dolphins showed evidence of population decline (1.5-2.0% per year from 2001-16), although there is some evidence of stabilisation more recently (from 2010-11 to 2015-16). As part of the review of New Zealand’s Hector’s and Māui dolphin Threat Management Plan (TMP) in 2018, a program of ongoing data collection and research, including a spatially explicit multi-threat risk assessment, is underway. This paper outlines data collection over the past 12 months and the research being undertaken to inform the review of the TMP. The TMP will be released for public consultation later in 2018.
