Michael Peryer, who leads bird spotting tours around the Waikanae estuary area, has released a children's book.
Kapiti Adventures of Sammy the Seal features a fur seal who goes an adventure from Kapiti Island, where it lives with family, over to the Waikanae River area.
The adventure focuses on various types of marine life, bird life, land creatures and human interaction before the seal returns home to tell its family about its adventure.
Mr Peryer wrote the story three years ago but then put it in a draw.
"Then I had my 80th birthday and thought 'if I don't do something about it I'm going to run out of time'."
