The Blue Lake Regatta has attracted its biggest field in recent memory with almost 700 rowers set to compete in Rotorua.
Defending champion Whakatane Rowing Club will look to repeat its success from last year, which saw it win the prized Dewar Shield.
The Shield is awarded to the club with the most points at the regatta and has a long history in New Zealand, having been contested since 1904.
Rotorua Rowing Club captain Glen Reichardt said about 680 rowers from 21 clubs would descend on the lake tomorrow and Sunday.
"It is one of the last semi-relaxed regattas of the season where clubs can get new rowers on the water and it is a relaxed environment. There is no eliminations and everyone races on the second day."
