Music and entertainment venues across Hawke's Bay say the discovery of Covid-19 in the community in Auckland will lurch them into another crisis.
Prime Minister Jacinda Ardern moved New Zealand to alert level 2 on Wednesday, with Auckland moving to alert level 3 following four cases of community transmission discovered on Tuesday.
While work and school is allowed to continue with physical distancing, gatherings of more than 100 people are now prohibited.
This includes weddings, birthdays, funerals, tangihanga and concerts.
The Paisley Stage owner James Rochester said Darren Watson's show on Friday night may be the first of many to bite the dust.
The Napier music venue owner said the calendar was filling up with shows before the news. He described it as something similar to a bombshell for the industry.
"Our gig on Friday has already been cancelled and a band from Auckland I was expecting will probably cancel soon I'd say too.
"There will be no need for sign in sheets at the entrance, masks, social distancing and so on, as we will be closed."
Roy Brown, owner of The Cabana, said a maximum of 100 people will be allowed at the Napier venue for the Fade to Black: Metallica Experience gig.
"We will adhere to spacing and limited numbers," he said. "But it's impossible for a music venue to control social distancing - that's up to the punters themselves.
"I've already sold 90 tickets, so that will be a bummer."
The production of Promise and Promiscuity, due to be held at Toitoi – Hawke's Bay Arts & Events Centre on Saturday and Sunday, has also been postponed.
The "lamentable" postponement of the new musical by Jane Austen and Penny Ashton has left Ashton on a "staycation" at an Airbnb on Marine Parade, Napier before her return to Auckland.
All tickets for the shows will be automatically transferred to a new date when set.
A Toitoi spokeswoman said all other events due to take place at the Hastings venue will be looked at under their Reducing Risk of Infection Plan and Pandemic Response Management Plan.
MTG Hawke's Bay announced that the Century Theatre, NZ String Quartet – Beethoven event will go ahead, with organisers contacting customers to let them know of the reduced numbers.
A spokeswoman said: "As yet we do not know what impact this will have in terms of domestic tourists coming to the region, but have certainly noticed a steep decline in visitor numbers today."
The Mystery of History exhibition will also be closed during alert level 2, given the high level of interactive elements in that exhibition. All other exhibitions are open to the public.
Meanwhile, Hawke's Bay Netball announced the cancellation of all junior netball in Napier, Hastings and Wairoa on Wednesday and Thursday.
Basketball Hawke's Bay also suspended miniball for Years 1 to 8 across Hawke's Bay, while restrictions on numbers, arrival times and contact tracing will be implemented in the Elite League and secondary school levels.
Central Football Hawke's Bay reminded those participating in training to limit numbers to 100, begin contract tracing and sanitise hands and equipment.
Te Mata School also announced the postponement of its parent-teacher evenings this week, despite school continuing as usual.
Hastings District Council speed limits review public information session scheduled to take place today has also been postponed.
