A bilingual book about the Māori creation story has won the highest accolade in children's literature.

Te Wehenga: The Separation of Ranginui and Papatūānuku by Motueka writer Mat Tait (Ngāti Apa ki te rātō) won the Margaret Mahy Book of the Year Award at New Zealand Book Awards for Children and Young Adults held at Wellington's Pipitea Marae.

Te Wehenga simultaneously tells the Māori creation pūrākau, which explains the beginning of the world, in te reo Māori and English.

Convenor of judges Nicola Daly praises the book's innovative approach to integrating both languages into the illustrations.

"The way that te reo Māori and te reo Pākehā are brought together closely feels like a metaphorical representation of the increasing bilingualism in Aotearoa."

Mat's book also won the Elsie Locke Award for Non-Fiction.

Duck Goes Meow by Juliette MacIver, illustrated by Carla Martell, won the Picture Book Award. Judges says the book is a joyous celebration of the unexpected that delivers a conclusion that surprises the animals in the story and readers alike.

Below, a white-knuckle survival story by David Hill, won the Esther Glen Award for Junior Fiction, while the Young Adult Fiction Award went to Iris and Me by Philippa Werry.

A Portrait of Leonardo, a vibrant retelling of the life of Leonardo da Vinci by Donovan Bixley won the Russell Clark Award for Illustration. The judges said this fresh, youthful approach to biography was a fluent and delightful visual feast for the eyes.

Kua Whetūrangitia a Koro by Brianne Te Paa, illustrated by Story Hemi-Morehouse won the Te Kura Pounamu Award for Te Reo Māori. Judges said the story's significance and context, and the author's use of te reo Māori, placed the book in a stratosphere of its own.

The NZSA Best First Book Award went to The Lighthouse Princess by Susan Wardell, illustrated by Rose Northey.
