"As the saying goes, you don't know what you've got until its gone" New Zealand National Fieldays Society chief executive Peter Nation said in a statement.
"The red light has been put on events across the world and behind every event is a huge supply chain of businesses that have been equally devastated by the effects of Covid-19. We don't want to lose more than we already have which is why we'll be going red today."
Fieldays contributed "significant money" to New Zealand's economy, and also provided 2000 fulltime jobs, Nation told The Muster's Andy Thompson.

Nation said had a quip ready those who asked him what the red colour meant.
"That's actually the colour of most of our bank accounts," he joked.
On a more sombre note, Nation said the red alert highlighted the "seriousness of where the industry sits".
"We haven't seen income come into our bank accounts for seven or eight months and for a lot of businesses that's not sustainable."
Ultimately, the events industry was important to all Kiwis, Nation said, and he encouraged people to get behind the #WeMakeEvents movement.
"The events industry in New Zealand in particular is a big part of our DNA ... whether it's rugby, a music concert, a field day ... it's very important for part of our wellbeing and our mental health and our connection with each other," he said.
"I'd love people to support us through social media and just be aware of the importance of the events industries to their communities."
