The Geronimo Stilton best-selling children's book series also featured strongly; it had eight titles in the top 20, including The Karate Mouse at No 8.
Down at No 30, but proving computer game addicts can tear their eyes away from the screen, was Matthew Needler's Minecraft Construction Handbook.
Auckland Libraries' regional manager Darryl Soljan said two things stood out from the findings - the popularity of the Geronimo Stilton series, which grabbed 33 spots in the top 100 books borrowed, and the success of books targeted at teens.
With The Fault in Our Stars, dystopian teen novels Divergent and The Maze Runner also landed in the top 10. Divergent and The Maze Runner have been transformed into hit Hollywood movies.
"It is interesting because people talk about teens not being engaged in books, then you look at this. They just seem to be stories that speak to how teens are feeling," said Soljan.
Total borrowings for the year were not available, but more than than 13 million issues were made last year, showing Aucklanders were getting their money's worth.
"Even if you value each [issue] at $20, that's $260 million worth of content going back to Aucklanders."
Meanwhile, Auckland Libraries regional collections manager Louise LaHatte said The Road Code was the item most-often lost from Auckland libraries, at 57 missing.
The Luminaries and children's book Nga Tamariki a Tane were the next most likely to have disappeared from the shelves, at eight copies missing each.
Books are loaned for free for 28 days and incur a $1-a-day fine if overdue.
