"Our most glorious librarian Margaret Mahy won the Junior Fiction Elsie Locke Award six times and she is once again a featured finalist," Ms Walsh said.
She said while there was a growing number of quality fiction books for children and young adults, the judges could only confidently present three books as finalists in the non-fiction category.
"It was disappointing to see a lack of attention to indexing and production in non-fiction submissions, however it allowed us to add two extra books into the excellent illustration and junior fiction categories."
Winners are announced at an award ceremony on August 5.
