I came across the Academy of New Zealand Literature which featured a list of 21 books written by Maori and Pasifika writers: http://www.anzliterature.com/feature/arent-reading-brown/. I have read none of them, but will certainly try finding some of these titles.
I’ve been looking for a copy of Skins: Contemporary Indigenous Writing, edited by Katerina Akiwenzie-Damm and Josie Douglas. This anthology, published in 2000, features work by indigenous writers from Canada, the United States, Australia and New Zealand. Unfortunately, a copy on amazon.ca is over $1,000!
