Kane Radford and Charlotte Webby made it a double at the weekend claiming honours in the 5km and 10km New Zealand Open Water Championships at Lake Taupo.
The pair both won titles in the 10km race on Saturday - which forms part of the Olympic qualifying stages - then followed it up with victory in the 5km race on Sunday.
It is the fifth consecutive year that Radford (Rotorua) has held both New Zealand Open Water Championship titles.
"That was the goal coming out here to try and do five in a row," Radford said. "It's something pretty special when you think about a stretch over five years, it's pretty impressive, and it's an honour to be able to come back and do it five years in a row."
Radford also took honours in the Western Australia Championships in December last year and said he was in a positive space for tasks ahead.
