If you are interested in learning more about the leopard seal. I see there are some talks on next week by leopard seal researchers. There are a few options.
13th August 6:30pm - at The Royal NZ Yacht Squadron
14th August 6:30pm - at the Flagship restaurant at Hobsonville marina
and 16th August 6:30pm - at the Flagship Education Centre in Wynyard Quarter.
They say its free. Might be worth going along and seeing what they have to say and could always ask them the hard questions.
