Racing on the first day at the World Rowing Championships on Lake Karapiro was postponed on Sunday because of windy conditions.
A strong south easterly wind whipping across the lake forced organisers to suspend racing after five heats on Sunday morning.
The organisers are also concerned about bad weather forecast for Thursday.
Organisers say it's likely the 27 races postponed on Sunday will be raced prior to Monday's scheduled races.
All Sunday ticket holders will get free entry on Monday.
Two New Zealand crews raced on Sunday morning before the cancellation.
James Lassche and Graham Oberlin Brown won their heat in the lightweight coxless pair and go straight into the final.
The lightweight women's double scull of Julia Edward and Lucy Strack came third in their heat and will go into a repechages on Monday.
