Wellington Phoenix's A-League season has been thrown into disarray after Prime Minister Jacinda Ardern announced that anyone arriving in New Zealand must self-isolate for 14 days in a bid to contain the spread of coronavirus.

The third-place Phoenix have seven games left in the regular season, with four of those fixtures scheduled to take place in Australia, including next week's games against Sydney FC and Newcastle Jets.

Although Sunday's match against Melbourne Victory will go ahead as planned, the Phoenix have conceded that staging future games New Zealand will be "impossible" under the new travel restrictions.

"The Wellington Phoenix has noted the Prime Minister's statement this afternoon, which imposes a 14 day isolation window for international arrivals into New Zealand due to the Covid-19 pandemic," the club said in a statement.

"As it stands, it will be impossible for any future Hyundai A-League Season 2019-20 games to be held in New Zealand, pending another government review in 16 days."

The strict border control protocols are a game-changer for New Zealand's only professional football club given they fly across the Tasman for every away game.

Phoenix players and staff would have to self-isolate for 14 days upon arrival back into Wellington, while the same goes for opposition teams travelling to New Zealand, making the current A-League schedule completely unworkable.

"The club has been making preparations for this eventuality and will make further announcements in due course.

"The club will continue to also continue to work closely with the League, FFA, New Zealand government and its partners as it works through this challenging time."

As of Saturday afternoon, there have been 200 confirmed cases of Covid-19 in Australia but just six in New Zealand.

Due to those figures, the Phoenix were hoping that they would not be placed under the same restrictions as the other 10 A-League clubs, who will likely have to play games behind closed doors from next week due to the Australian government's impending ban on mass gatherings of more than 500 people.

"In terms of the league, the league is taking direction from the Australian government but what that means for the Phoenix, we will take our direction in terms of what we can and can't do in terms of mass gatherings from the New Zealand government," general manager David Dome told Stuff on Saturday morning, prior to the Prime Minister's announcement.

"At the moment it's very much business as usual but things can change very quickly."

And change quickly it has. A decision on the Phoenix's season and how it may look moving forward will have to be made before the team travels to Sydney on Tuesday.

To further complicate an increasingly complex situation, the Phoenix's star player Ulises Davila was due to fly home to Mexico after next Sunday's clash with the Jets to meet his newborn son.

If Davila was to leave New Zealand, he would have to self-isolate for 14 days upon his return, leaving him in an extremely difficult position as a first-time father.

Prime Minister Ardern said the government will review its new travel restrictions in 16 days.
