CRNZ high performance manager Grant Restall said: "Ben has taken a short-term role for two months with CRNZ going through to the world champs," he said. "He's working under Gordon, who is leading the campaign with Ben's help. Ben is doing the day-to-day coaching and having input into the overall plan."
Teneale Hatton, Aimee Fisher, Jaimee Lovett and Caitlin Ryan will represent New Zealand in the Olympic K4 discipline. The crew finished seventh at their most recent World Cup in the Czech Republic.
In the lead-up to the year's pinnacle event, they trained in Portugal at a centre 150km south of Porto sponsored by kayak manufacturer Nelo. The venue enabled them to paddle three hours in several directions on the lake.
Carrington remains New Zealand's best medal hope in Olympic-standard disciplines where she will contest the K1 200m and 500m.
Hatton is a medal contender in the K1 1000m and 5000m events which she won in the Czech Republic. She's the defending world champion over 5000m.
Darryl Fitzgerald, Marty McDowell, Jarrod Fitzgerald and Zac Quickenden will contest the men's K4 1000m and Scott Bicknell will race the K1 200m after his K2 partner Andrew Roy withdrew with injury.
