Hastings Mayor Lawrence Yule has praised the efforts of Splash Planet staff after a brawl broke out at the Hastings water park at the weekend.
A police representative said police were called to Splash Planet about 3.45pm on Saturday, after reports of more than 10 people fighting.
One person was arrested for disorderly behaviour, she said.
Mr Yule said an Auckland sports team was visiting on the day and two men got into a scuffle inside the facility.
That was sorted out, he said, but then the fight continued out in the car park where the arrest was made.
