Mahe Drysdale and Robbie Manson have eased to single sculls wins in the opening-day heats at the national rowing chamionships on Lake Karapiro.
The two world class rivals qualified automatically for a high-profile final on Saturday, avoiding today's repechage race.
Manson clocked the fastest time in the second heat, in 7 minutes 16.29 seconds to hold off Jordan Parry, a member of the winning men's quad at last year's world under-23 championships.
Two-time Olympic champion Drysdale had no real challenge on Tuesday in the opening heat, easing across in 7min 20.06sec,
New Zealand Rowing announced this week they will send two single scullers to European-based World Cup meetings later this year - almost certainly Manson and Drysdale - but only one will go to September's world championships.
Drysdale has been well beaten by Manson in their two previous meetings this summer, with the 39-year-old still working his way back to full fitness after taking a year off following his Rio Olympics triumph.
