Artist Dick Frizzell never imagined his book Pukeko in a Ponga Tree would become New Zealand's biggest-selling children's book.
"I'm deeply impressed. Who would have have thought?" Frizzell said.
The award-winning book, written by the late Kingi Ihaka and illustrated by Frizzell, was a Kiwi adaptation of the classic song The Twelve Days of Christmas.
It replaced original items such as turtle doves with iconic kiwiana including haka lessons, fish-heads and kumara.
Frizzell's brightly coloured illustrations remained modern even though they were drawn about 30 years ago.
