WOW is New Zealand's largest theatrical production, attracting about 60,000 people annually.
It is also a sought-after competition for international designers working at the cutting edge of fashion, art, design and costume, alongside students and first-time entrants.
Since 2005, when WOW first opened in Wellington, almost 6800 people have worked on the show, attracting a total audience of more than 700,000.
When the nationwide level 4 lockdown was announced, organisers said a lot had already begun to get the show ready.
"When the Government announced the level 4 lockdown on 17 August, the TSB Arena was a hive of activity with the stage being built, rehearsals underway, models being fitted into garments and character costumes being made."
The show was cancelled last year due to Covid-19.
There are 547 cases in Auckland and 15 in Wellington. Forty-two cases are yet to be linked to another case or sub-cluster.
Organisers are currently working with Strategic Partners, Wellington City Council and
WellingtonNZ to find possible postponement dates.
Those who have already purchased tickets are asked to wait until a confirmed postponement dates. Tickets then will be available for a refund or transfer to the new dates.
The event is worth nearly $28 million to the local economy and is considered an economic highlight for the city's retail and hospitality sector which, for some, eclipses the busy Christmas trading period.
