Research undertaken by the trust began in 1995 as part of foundering trustee Shaun McConkey’s 'master of science' thesis

The trust funded equipment for Shaun to use during his research

Individual Identification, Population Dynamics and Moult of the New Zealand Sea Lion at Otago

The trust facilitated and supervised several student projects

This study focused on the breeding behaviour of New Zealand sea lions at Otago Peninsula. Timing and location of births were recorded as accurately as possible for the 2003/04 and 2004/05 breeding seasons. Birth dates at Otago were similar to peak pupping dates at the main breeding colonies. Foraging cycles and attendance patterns of mothers were determined through 10 consecutive days of observation each month from March-June. Otago females were found to have, on average, shorter duration cycles than females at the Auckland Island breeding colonies. This may suggest a better foraging environment at Otago. In an effort to understand the dynamics involved in the formation of breeding colonies, interactions between females ashore were recorded to investigate the gregarious behaviour of New Zealand sea lions. At the Auckland Islands females gather for pupping and then disperse, compared with Otago where they disperse prior to pupping and converge later.
