THE FUTURE of AFL games in Wellington is uncertain, with the New Zealand capital's local government unwilling to guarantee its support for future matches.

Funding from the Wellington City Council is seen as critical to the success of the St Kilda deal, which has a review clause after three years of a five-year contract.

It is speculated the Saints make up to $500,000 annually from the agreement.

Only 12,125 people attended Saturday's third game at the city's colloquially named 'Cake-tin Stadium' between St Kilda and Carlton.

"Our agreement with St Kilda and the AFL makes provision for all parties to review the agreement after the 2015 match," WCC spokesman Richard MacLean confirmed to AFL.com.au on Tuesday. 

"WCC, along with St Kilda and the AFL will conduct our respective reviews in the coming weeks," he said.

AFL.com.au understands the WCC will also assess whether Anzac Day is the right day for the game, and could be open to considering other dates.

The AFL conceded it was disappointed with Saturday's crowd.

"We would hope for more," football operations general manager Mark Evans told reporters on Monday.

"You would like to see 20,000 people at the venue and come away saying it has been a great success," Evans said.  

"I think it has been outstanding for us to showcase the game in New Zealand and particularly to pay tribute to the Australian and the New Zealand armed forces on Anzac Day.

"That should be a winning formula, but it is something we will review with St Kilda and the folk in New Zealand to see where it goes." 

This year's attendance was a drop on 2014, when 13,409 watched the Saints lose to the Brisbane Lions.

In its first year, when the Saints lost to Sydney Swans, 22,565 attended.

It is understood around 2000 fans travelled from Australian for the game, and the WCC is pleased with the tourism impact.

However with the game failing to capture the imagination of locals, it's believed the council will reassess whether it should continue backing the project financially.

St Kilda remains committed to the New Zealand market, with chief executive Matt Finnis telling reporters after Saturday's loss that winning was "the missing piece to really solidify Wellingtonians behind our club."

Carlton defeated St Kilda by 40 points.
