As a last day sale special on Sunday, a plastic bag filled with the pre-loved items was being sold for $5.
Deejaee McLean had travelled form Tokoroa especially for the book sale, collecting a number of bags to take home.
"I'm trying to hold back but I've got five bags already," Miss McLean said.
Secondhand books were a more exciting shop for her as there were more surprises.
"You find books you can't find brand new and they're cheap."
Tauranga brothers Blair and Aiden Mabey and cousin Ethan Clare were on the hunt for adventure books and some fresh material they couldn't find in their school library.
Blair was happy to have found some Paul Jennings books among the stacks.
"I'm very interested in these books," he said, as a keen reader.
Leftover children's books and magazines would be donated to the hospital, Mrs Hofland said.
