After the unprecedented success of their K4 boat last year - Fisher, Ryan, Kayla Imrie and Jaimee Lovett finished fifth in Rio - selectors have given national women's coach Rene Olsen two of the larger boats for the World Cups.
Carrington replaces fellow Whakatane paddler Lovett - now retired - in one boat, while Kim Thompson, Briar McLeely, Rebecca Cole and Britney Ford will form a second quartet, competing in both K4 200m and 500m events at both rounds.
"Being able to put two quality K4 boats on to the world stage is a big achievement for a country the size of New Zealand," Olsen said.
"I'm incredibly proud of both the depth we've developed and that our best athletes have the ambition to be a part of the team boats now. The exciting part is that there's still a long way to go."
Carrington and Fisher will also combine in the K2 200m in Portugal, alongside McLeely and Imrie, with Carrington and Fisher also racing the K2 500m alongside Thompson and Cole. Fisher and Ryan will race the K2 200m in Hungary, with McLeely and Imrie, and Carrington and Ryan will combine for the K2 500m, again joined by Thompson and Cole.
The New Zealand team will return after the second World Cup at the end of May, before a new team will be named to tackle the world championships in Račice, Czech Republic, from August 23-27.
