"There is such vitality in this year's longlist, demonstrated by a diverse group, and including young and first-time authors. Half of this year's Jann Medlicott Acorn Prize for fiction longlistees are debut novelists, which is extraordinary. They sit alongside some of our greatest living writers," Todd said.
"There's a year's worth of reading here for those seeking considered perspectives on our modern zeitgeist, for readers wanting to be wowed by the beauty of art and nature, or for those wanting to escape into imagined realities.
"With writing and publishing of this calibre, it's no surprise that New Zealand's book boom continues."
Revenue from sales of New Zealand-published adult books captured by Nielsen BookScan in 2020 was up 12.5 per cent on the year before, despite the challenges of the pandemic.
Submissions to the awards have also increased by 16 per cent over the past two years.
The Illustrated Non-Fiction category also has a new sponsor this year, with Booksellers Aotearoa New Zealand securing the naming rights for the next five years.
Booksellers Aotearoa New Zealand chairwoman Juliet Blyth said the association – which celebrates its centenary this year – was delighted to support the awards.
"Booksellers around the country hold these awards in high esteem, and the impact the awards have on sales of New Zealand books is immediate," she said.
"Throughout 2020, booksellers around the country enjoyed the support of many New Zealanders reading more and buying locally. We wanted to demonstrate our appreciation, on behalf of our members, by giving back to the industry, the writers, the illustrators and the publishers who have created so many wonderful stories for booksellers to put on their shelves."
The 2021 Ockham New Zealand Book Awards shortlist of 16 titles will be announced on March 3.
The winners, including the four MitoQ Best First Book awards, will be announced at a public ceremony in May during the 2021 Auckland Writers Festival.
