The search for a missing swimmer near Mount Maunganui will resume at the break of dawn on Monday.

The man failed to return to shore just after 10am on Saturday after swimming with two others at Marine Parade.

Police report that today's search that involved the Police and the Surf Life Saving Club members was unsuccessful and nothing of interest was located.

"The rough sea conditions with swells of up to a metre-and-a-half proved challenging for the search team as they covered areas from Mount Maunganui to Omanu," says a Police spokesperson.

Police will reassess the weather condition tomorrow and decide on whether to widen the search area tomorrow.

The TECT Rescue Helicopter was also part of the search on Saturday.

Lifeguards were alerted by police to a missing swimmer along the Mount Maunganui coast just after 10.30am on Saturday.

Call-out squads from the Mount Maunganui Lifeguard Service, Omanu and Papamoa Surf Clubs responded and up to six IRB (inflatable rescue boats), a jetski, two all-terrain vehicles and more than 30 lifeguards were asked by police to search the surrounding area.

Police continue to provide support to the man's family.
