NPOA-seabirds 2013 gives high priority to research to understand the effects of fishing-related mortality on seabird species at highest risk and on factors that are leading to the greatest level of uncertainty in the risk scores.

Black petrel is the species estimated to be at most risk from commercial fisheries but there is considerable uncertainty in this estimate because of uncertainty about capture rates in longline fisheries, adult survival, juvenile survival, population size and distribution.

Overall Objective:
To collect information on demographic parameters to reduce uncertainty or bias in estimates of risk for black petrel.
Specific Objectives:
1. To collect information on population size, adult survival, age at first reproduction, and key demographic parameters for black petrel to reduce uncertainty or bias in estimates of risk.
2. To sample Medium Grade habitat on Great Barrier Island/Aotea to increase the precision of estimates for the population size within this habitat grade.
