A section of Papamoa Beach was cleared yesterday when a 2m shark swam within metres of a group of people fishing on the shoreline.
Police and lifeguards were alerted to the sighting and about 20 people line-fishing at the spot were urged to stay away.
The shark, thought to be a bronze whaler, came within 10m of the shore on the eastern side of the Bay of Plenty beach about 10.15am.
Papamoa Surf Life Saving regional guard patrol captain Shaun Smith said there had been several shark sightings this week but the beach remained open.
He said the beach would be shut if the sharks began circling or swimming towards the flags, or if the water was packed.
