The awards began in 1982, as the
New Zealand Government Publishing Awards, with two categories, Children's Book of the Year and Picture Book of the Year. A non-fiction award was presented in 1986, but not in 1987 or 1988, the final years of this incarnation of the awards. No awards were presented in 1989. In 1990,
Unilever New Zealand (then the New Zealand manufacturer of
Aim toothpaste) restarted the awards as the '''AIM Children's Book Awards'''. There were two categories at that time, Fiction and Picture Book. Second and third prizes were originally awarded, though these were replaced with honour awards in 1993, presented at the judges' discretion. In 1997, the awards became the '''New Zealand Post Children's Book Awards''', and another new category was added, the New Zealand Post Children's Choice award. In 2015 the title of the awards changed to the
New Zealand Book Awards for Children and Young Adults. At this time the awards were administered by Booksellers New Zealand, an industry organisation, and were presented at the end of a 10-day festival organised by the
New Zealand Book Council each May. In 2016, the awards merged with the
Library and Information Association of New Zealand Aotearoa (LIANZA) Awards, and became administered by the New Zealand Book Awards Trust. As a consequence of the merge, the Junior Fiction category prize was combined with the
LIANZA Esther Glen Award for junior fiction and the Non-Fiction award was combined with the
LIANZA Elsie Locke Award for Non-Fiction]. In addition, two new categories were introduced via the LIANZA Russell Clark Award for Illustration and the LIANZA Te Kura Pounamu Award for works written in
te reo Māori (the Māori language). ==Prizes==
