A young lifeguard rescued a girl after she and two family members were swept off a sandbank into a rip at Arataki.
The section of beach is unpatrolled but lifeguards roam the area on hour intervals from the Omanu surf club base.
Lifeguard Flynn Weatherall, 17, was waved down in the area by a member of the public while he was checking the area who alerted him to three people who appeared to be caught in a rip at 1.30pm on Sunday.
The mother and two children, aged about 10 and 13, had got caught in a rip which “happened pretty fast”, Weatherall said.
He decided to do a welfare check and took a tube and fins into the water.
