Riewoldt, 29, said Wellington had the opportunity to show everyone that the AFL should be taken to other offshore locations.
"I suppose this is in its infancy at the moment. But I definitely think that's the goal of the AFL and this is obviously the first step towards that. So if we can make it work and the people of Wellington can get right behind it, our supporters can get right behind it and it becomes mutually beneficial for everyone involved then I can't see any reason why the game won't progress and eventually be played elsewhere. But this is going to be a real litmus test I think so lets see everyone get behind it and make sure it comes off."
Westpac Stadium has a capacity of 34,500, which is the average attendance of an AFL game in Australia and St Kilda's club boasts more than 35,000 members.
The Saints finished ninth this year, missing the top-eight playoffs by eight points but were grand finalists in 2009 and 2010.
Wellington City Council believe the agreement will strengthen transtasman ties and boast the economy in the capital with the expectation that numerous Australians will travel to these shores for the game.
Saints ruckman Ben McEvoy, who stands an imposing 2m tall, said he went to Westpac Stadium today and was impressed with the surroundings.
"We were there this morning and it's spot on," the 23-year-old said.
"The surface is great. We met the curator there and he's doing a fantastic job and they're gutting the rooms in there so they'll be brand spanking new. So it'll be sensational; location couldn't be better, you can nearly walk there from where we will be staying so it'll be a couple of minutes bus ride. It's pretty close to the airport too. Everything stacks up, it's world-class."
Wellington's world-famous wind is likely to remind McEvoy of home too.
"I'm not a huge fan of it but where we train back in Melbourne we are pretty well used to it."
