Mahe Drysdale's the only New Zealand rower who could be added to the national team to compete at the World Rowing Championships at the end of next month in South Korea.
The five-time single scull world champion and Olympic double medallist faces a time trial on Friday and Drysdale has to impress the selectors, as he continues his return from a six-month sabbatical from the sport.
An unchanged team has been named for the World Championships, with a total of 38 rowers in 13 boats.
No trial will be held as the selectors feel the crews selected for the World Rowing Cup series performed well.
Olympic double sculls gold medallist Joseph Sullivan has made himself unavailable for selection, but intends returning for the summer squad in October, in preparation for the 2014 season.
