Dawson said these types of incidents are always distressing for staff and members of the public.
"As a result we have temporarily closed the aquatic part of the Stanmore Bay Leisure Centre for the rest of the day. Staff are also being provided with support," he said.
The leisure centre posted on Facebook, stating that due to an emergency situation, the pools, sauna and splashpad are closed for the rest of the day.
"We apologise for the inconvenience and will advise any change. Thank you for your understanding," it wrote.
Stanmore Bay Pool and Leisure Centre is located on the Hibiscus Coast, about 40 minutes from Auckland.
