The second K4 crew comprises the up-and-comers, Briar McLeely , Rebecca Cole, Britney Ford and Kim Thompson, daughter of 1984 Olympic champion Alan Thompson. They will race in both 200 and 500m distances at both cups.
"We're really proud of the progress the younger crew has made since joining our high performance squad and this is their chance to display that improvement on the world stage," Canoe Racing New Zealand chief executive Mark Weatherall said.
The eight women will split into four pairs to race over the 200 and 500m distances at both cups.
A new team will be named for the world championships in Racice, Czech Republic in August.
"Being able to put two quality K4 boats onto the world stage is a big achievement for a country the size of New Zealand," K4 coach Rene Olsen said. "I'm incredibly proud of both the depth we've developed and that our best athletes have an ambition to be a part of the team boats now. The exciting part is that there's still a long way to go."
