Big wins to the women's Black Sticks and rugby sevens sides highlighted the earlier part of the morning, while high winds scuttled any chance of further rowing success.
Two New Zealand crews were to contest their first round heats - the women's pair of Rebecca Scown and Genevieve Behrent, and lightweight women's double scullers Julia Edward and Sophie Mackenzie.
Their races will be pushed back one day as officials set about re-jigging the schedule.
The women's Black Sticks began their Olympic campaign in style after defeating a tough South Korean side 4-1.
Up against the eighth-ranked side in the world and one the Black Sticks had an even 7-7 all-time record against, the result was the perfect momentum-builder as group play began today.
The women's rugby sevens side progressed to the quarter-finals of their competition after defeating France 26-7 early this morning to top their pool.
They'll now take on the USA later this morning to decide which country will contest the semifinals.
The high winds have also affected play in the tennis tournament with all matches except those on centre court currently delayed.
In the pool Florida-based New Zealand backstroker Corey Main powered to a sub 54-second personal best in winning his 100m heat. Main, 21, clocked 53.99 seconds, to book a spot in the semifinals later today.
Kiwi freestyler Matthew Stanley failed to qualify for the semifinals of the 200m event. Swimming in the third of six heats, Stanley finished second in his heat clocking one minute 47.37 seconds, fractionally outside his New Zealand record of 1:47.09 set two years ago.
That was the 20th fastest time but not fast enough to be one of the 16 qualifiers for the semifinals. Lauren Boyle also failed to advance past the heats in the 400m event, finishing fifth in her heat.
Elsewhere, the entire Russia team has been banned from competing in the Paralympic Games in September as punishment for the country's systematic doping program.
