A stolen playground slide was among guns and methamphetamine found by police during a search in Marlborough.
Three people are facing charges after searches in houses in Blenheim and Waikawa on Wednesday.
Methamphetamine, 24 firearms, cannabis and stolen property including the slide were discovered.
The slide is believed to have been taken from Burleigh Park in Blenheim two years ago.
A police spokeswoman said the slide has been returned to the Marlborough District Council.
