Lochie Grant (7), of Dunedin, came up with the idea of a "Tri-brary" which would add sports gear and DVDs to the books that could be borrowed from the library reading room.
Lochie's father Craig Grant said their family had a crib in Naseby which they visited regularly.
His son thought being able to borrow not just books but also games, sports gear and DVDs would enable holiday-makers to make the most of the summer both indoors and outdoors.
"People ... might go up there and stay for a week, but not have all the stuff to entertain the kids."
People could "donate, borrow, bring back" a selection of items, Mr Grant said.
Naseby librarian Dawn Lowien said she "couldn't believe" how many items were available.
There were cricket bats, racquets, crossword puzzles - "too many things to mention".
It was the first time she had seen anything like this, but was very keen on the idea when Lochie suggested it.
With a recreation ground just across the road and many children who came for the holidays, it would be very popular, Mrs Lowien said.
