A small boat with two people on board overturned in heavy surf near the mouth of the Greymouth River this afternoon.
At about 12.25pm the two males were thrown into the water but the boat righted itself. The men climbed back aboard and attempted to bail out the water but were overturned again.
Both boaties were in the water for about 40 minutes. One 64-year-old male was semi-hypothermic and had cuts to his leg. The other 52-year-old male was cold with a sore shoulder. Neither required hospital treatment.
An 18-year-old male and 24-year-old male were body-boarding nearby and, at the request of the attending Police, they swam to the boatees and helped keep them afloat until rescue arrived.
The males were wearing lifejackets and had a marine radio. "They were well-equipped but in the wrong place" said a Police spokesperson.
