Three people have been rescued after their boat capsized trying to cross the Kawhia Bar, south of Raglan in Waikato.
The boat had three people on board - two men in their 30s and a 14-year-old boy.
All three were wearing lifejackets.
Police said there was a local charter boat nearby that was able to rescue them.
Police said the skipper tried to do everything right, but the fact that his boat capsized indicates how dangerous and unpredictable the bar can be.
