Auckland Council's new rule on wearing lifejackets in small boats kicks in at Labour Weekend but needs a law change before it can be enforced with the issuing of tickets.
At present its Navigation Safety Bylaw requires only that flotation devices be carried on small boats for everyone in times of heightened risk and when directed by the skipper.
Failure to comply risks a $200 fine.
But from October 25, a bylaw change affecting boats 6m and under makes wearing lifejackets mandatory.
"Everyone must wear a lifejacket but if the skipper feels it's safe to remove it, they can," said councillor Calum Penrose, who headed the bylaw review. He said the new rule allowed people to swim off their boats in calm conditions or to sleep on board without the discomfort of wearing a lifejacket.
