This year Aucklanders are keen to get their hands on My sister's keeper author Jodi Picoult's latest release Small great things - 400 people had requested the book as at April 4.
However Lee Child's Night school and Joanna Trollope's City of friends topped wait lists across the country with 422 and 308 people in Auckland, Christchurch and Dunedin placing the respective books on hold.
Carolyn Robertson, head of libraries and information at Christchurch City Council, said often books became popular because they had advertised extensively, were connected to a TV series or featured on bestseller lists in New Zealand and overseas.
She said the central character in Child's series, Jack Reacher, likely increased his books' popularity.
"In many ways Jack is a similar to James Bond, a hero who manages to get out of any scrape or situation he gets himself into. The books follow a standard recipe and provide escapism for the reader."
Auckland Libraries' head of content and access, Catherine Leonard, said crime and thrillers were favourites for recreational reading and in reviews on the libraries' online catalogue readers described Lee Child's as "fast-paced", "non-stop action", and "ingenious".
Kiwi writer and University of Auckland senior lecturer in creative writing Dr Paula Morris said she wasn't surprised to see the names of Child, Kinney and Trollope on the libraries' most popular lists because they were international writers signed to big publishers.
"Books from the big English-language markets (US and US) often have massive marketing budgets, and if these books are made into movies (like the Jack Reacher books and The Girl on a Train), it means even more international marketing, often with millions of dollars spent.
"It's not a surprise that these are popular books with borrowers. Genre fiction - thrillers, mysteries, romance - is popular everywhere, and has been for a long time. Fantasy is still popular with younger readers, in particular."
The University of Otago's Jacob Edmond, associate professor in English, agreed that it was no surprise that these books topped the most borrowed list.
"The popularity of genre fiction is not new and hardly unique to New Zealand," he said.
While the number of print books being issued in Auckland libraries was slowly declining, e-book issues were increasing.
"We think there are a combination of factors , including the fact that more people get certain types of information online," Leonard said of the factors affecting the drop in print book loans.
"Although loans may be slightly down, our figures show that the duration of people's visits to our libraries are increasing, as is the use of our Wi-Fi."
Although most of the services libraries provide are free to members, late returns and lost items cost Kiwis big time in the year to June 2016 when libraries in main centres charged $3,306,191.07 in fines and penalties.
Leonard told the Herald many factors could be impacted increase in fines collected.
"These include a new fee for the not collecting requested titles, better recovery of fines at our libraries and a corresponding reduction in debt recovery of fines."
The book that disappeared from shelves most frequently in Auckland - 20 times - was The official New Zealand road code: your guide to becoming a safe and responsible driver.
Libraries in Auckland had a security system to prevent books from going missing, Leonard said.
All books, DVDs, CDs and console games had RFID tags and all libraries had RFID security gates.
If they hadn't been desensitised during check-out the items' tags attached to the items set off an alarm when taken through the gate.
