Twelve teams from Rotorua, Wellington, Waikato, Auckland and Tauranga will play eight-minute halves with non-stop games between 9am and 7pm on Saturday and between 9am and 4pm on Sunday.
Water polo athlete Cameron Hayes was looking forward to this weekend's event, playing with his Tauranga-based Piranha team. However, after suffering a shoulder injury on Wednesday he was no longer able.
The 23-year-old who has been playing water polo for about 14 years would still be at the tournament though, supporting his teammates and the event that he hopes will showcase the sport to a wider group of people.
"It's a good way to show the sport around Tauranga," Hayes said.
Hayes said having it run similar to a sevens rugby competition, as a fast-paced and shorter version of a regular water polo match, would show the physicality and the action involved with the sport.
"It's certainly about attracting people down to the event to see what it's all about."
He says a good mix of athletes are taking part including new and old players, some of New Zealand's top athletes and those who were coming out of retirement. He says it will be an exciting event to watch and hopes it goes ahead as planned this weekend.
