"We've seen a steady increase in population in that particular area. The dairy and the cafe across the road have helped in the increase but also the housing in that particular area," Mr Sefton said.
He said lifeguards were responding to the demand not just with the tower but also with an extended patrol season of three-and-a-half weeks.
Last summer lifeguard callouts and rescues reached record breaking levels, with 171 rescues performed from Mount Maunganui, Omanu and Papamoa clubs.
Mr Sefton said Tay St beach was not overtly dangerous but had been a comparatively high-risk area in previous years because of the lack of a lifeguard base. "Last year, the whole coastline between Leisure Island and Papamoa East was so busy."
