Despite a nippy first weekend of summer, 299 people stripped off at Papamoa Beach near Tauranga in a bid for the Guinness World Record for skinny dipping at a single venue.
The record - currently at 413 people - was also tackled at Christchurch's Sumner Beach on Saturday but they also fell short of the target, with a turnout of only 226.
But participants said it was all a bit of fun, despite a few last-minute doubts.
"There were a couple of things that made us half think of not doing it, but we did it in the end anyway," one skinny dipper from England told 3 News.
For the record to count, Guinness World Records required all swimmers to be in the water at the same time for a group photo.
