Phoenix chief executive Tony Pignata is predicting a sell-out at the 34,500-capacity Westpac Stadium with more than 29,000 tickets sold in the past five days.

Pignata said: "I said it was the hottest ticket in town and it sure is.

"It's going to be a memorable day. It's our last home game of the year. What better way to finish the season with a capacity crowd at Westpac Stadium.

"Win or lose it's going to be a big day for football lovers."

More than 24,000 people roared the Phoenix to victory against Perth Glory in a nail-biting match last weekend that saw Wellington go through 4-2 on penalties after being locked 1-1 at the end of extra time.

It was a record crowd for an A-League match in New Zealand following the 20,000 that packed into AMI Stadium in Christchurch for the Round 25 clash against Adelaide.

The final round of the regular season saw just over 14,000 turn out to watch the Phoenix defeat Central Coast 3-0 to secure a home tie in the first weekend of A-League finals football.

Pignata acknowledged the good crowd sizes, coupled with the Phoenix reaching the playoffs for the first time, would help the club's push for a 10-year A-League licence which it has yet to be granted.

While it has a FIFA exemption to compete in the Australian competition next season no long-term deal has been struck as the Asian Football Confederation, to which Football Federation Australia is aligned, has so far been reluctant to allow the New Zealand team to be involved beyond next season as it is part of the Oceania Football Confederation.

"We've ticked a lot of boxes this year and we're hoping the AFC together with the FFA see that and grant us a licence," said Pignata.

"All we can do is continue doing what we're doing on and off the field and let the powers that be sort it out.

"But it is difficult because we're trying to entice sponsors for long-term deals. At the moment we've got a one-year licence.

"We're hoping that it will be sorted soon and we get the right to continue to play in the A-League.

"I can understand sponsors wanting to know if we're going to be here for future years. They don't want to invest for one year so I'm hoping that within the next couple of months it's sorted."
