Work is under way to fix an issue at Baywave which has affected the water temperatures.
Contractors were at the Mount Maunganui pool complex today after Bay Venues found the bore system, which provided heating to the pools at Baywave, unable to maintain consistent water temperatures for all pools.
The bore was shut down, allowing investigations and remedial works to take place today.
Acting chief executive of Bay Venues Justine Brennan said the reinjection bore was an integral part of the infrastructure used to heat the water and air at Baywave.
"What this means for our customers is a noticeable colder water temperature, with the smaller pools losing heat at the fastest rate," she said.
