However, just four NZ books make the Top 100: The Luminaries, The Cloud Leopard's Daughter by Deborah Challinor, perennial favourite The Edmonds Cookery Book and Dr Libby Weaver's Women's Wellness Wisdom. MacKenzie would certainly like to see more home-grown titles make the list.
"It's always been a challenge to get New Zealanders to read New Zealand authors and that's a real shame," she says, adding that those who avoid NZ fiction are missing out on some top-quality and reads. "The opportunities are there for people to discover these books; there's more mainstream fiction than ever before and much of it is extremely good."
"Joan's picks" - MacKenzie's recommended reads - feature strongly on the list. She says it's a way to promote new books and authors and cites I Am Pilgrim (number 3) as an example of this.
"Then readers say, 'well, I read that and liked it so what would you recommend that's similar and I might enjoy?' so it's a very useful way to bringing new authors to attention and of pointing out what may be the next big thing."
The most popular author is Jodi Picoult, who has six separate titles in the Top 100; more than any other writer. But nearly one third of the books to the Top 100 are newcomers, a mix of new releases and old favourites like To Kill a Mockingbird and The Edmond's Cookery Book.
"We're especially pleased to see the young poet Rupi Kaur, a huge success at this year's Auckland Writers Festival, receive so much attention," says MacKenzie. "Her book Milk & Honey (70 in the Top 100) has resonated with readers around the world and New Zealanders have equally taken her to their hearts."
As the Top 100 list is released, a new survey - made public just days before - has also revealed more about our reading habits. The first survey of its kind, Book Reading in New Zealand was carried out online, getting just over 2000 responses, by Horizon Research for the NZ Book Council.
It confirms we are a nation of book lovers with readers clocking up an average of 20.6 books a year. However, the survey also showed around 394,000 adult NZers didn't read a single book during 2016. A third said they didn't have time to read; a quarter said they didn't like reading and the remainder felt it was easier to watch movies based on a book.
NZ Book Council patron Albert Wendt says getting reading on the national agenda is a crucial step in breaking the poverty cycle. Reading for pleasure is linked to benefits like improved academic performance for school-aged children.
"There are already some excellent initiatives out there such as the Book Council's Writers in Schools and Writers in Communities programmes, but more needs to be done," says professor Wendt. Encouraging reading, particularly reading for pleasure, is critical to ensure all New Zealanders can be part of our nation's prosperity."
But there, was, perhaps, good news for NZ books; at least half of the respondents to the Book Council's survey had read at least one Kiwi author in the past 12 months.
The Book Council will use information for the research to bolster existing strategies for increasing the number of lifelong readers and for encouraging greater consumption of NZ fiction.
