Even the Piha event cancelled, we have had 5 cases and it's been so long since a major event in NZ
In terms of timing this is the best time of year for offshore or glassy as most the year it's 3m & onshore.
If the postpone then change venue to suit the prevailing season conditions to either Raglan or mobile event on Taranaki coast

Also the first America's cup AC75 Event in Italy is off and hopefully the England event happens.
There will be a lot of sport happen without any spectators being at the event.
STAY SAFE
