Five rookie lifeguards found themselves putting their training to use to rescue three people from deep water on Saturday.
The 13-year-olds were at Ocean Beach, north of Whangarei Harbour, for a training session and were watching the water after club captain Julian Pitman noticed some strong currents.
Two children and their mother were swimming between the flags but quickly found themselves sucked into a hole of deep water, Mr Pitman said.
Mr Pitman and other senior lifeguards supervised from the beach while the rookies performed the rescue.
"They did well, they worked together. It was great because I didn't have to get in there," Mr Pitman said.
