Samoan architectural designer, Lei Toetu, started the not-for-profit project 'The Book Stop', so people can share and swap books.
Since launching in the suburb of Mt Roskill, there's been demand for more fridge libraries in disadvantaged parts of South Auckland, Mr Toetu said.
"There are a lot of things you can do with these types of fridges, but this is something that will benefit the whole community. It's not going to landfill and it's still being used.
"It's actually being used longer than what it was designed for."
