Thinking back to one of his many tours, he remembered Vanessa Owens, from Raumati Beach, who had told him she was an artist and enjoyed painting birds.
She had been on the tour to get some inspiration, he recalled.
"I needed an illustrator, and didn't know who to get, so I emailed Vanessa and asked if she would be interested in helping with the book."
The book features some photographs from Roger Smith, from Waikanae Beach, and has been printed by Precise Print in Paraparaumu.
Mr Peryer said the story is the first in a series of five.
"The story I wrote was about 3000 words, so it has been cut it down to five different books.
"The second one I've got written but I haven't got it illustrated.
"I'm waiting to see what happens with this [first] one."
A lot of the book extracts have been drawn from his monthly newsletter, which he has been writing for about 15 years, and which focuses on life in and around the Waikanae estuary.
