On Sunday, NZ suffered a narrow loss to South Africa in the SANZ Trophy.
The event is contested annually between the two teams in the build up to the World Junior Championship.
Both teams went into the final with six surfers each, however South Africa amassed 8890 points to NZ's 8720 once the finals were completed. After the SANZ Trophy, the team took part in the Olympic-style parade of nations through the streets of Pedasi.
Team captains Ben Poulter and Jayda Martin Fitzharris took the stage for New Zealand, while the team performed an impromptu haka.
The swell is expected to increase over the next three days with clean conditions forecast.
Surfing kicks off each day at 1am NZ time.
