St Kilda and the Sydney Swans will compete in the first home-and-away game outside Australia and are seeking commensurate effort from their players to mark the occasion.
Watters, who was involved in two Anzac Day games as an assistant coach at Collingwood, said his players had the chance to "show what they stand for" on an international stage.
"This sort of opportunity can help build the culture of your club," Watters said.
"What we're looking for is real honesty in the contest.
"On this particular day, on this particular stage, so many people watching … it's an opportunity for players to show what they stand for on both sides.
"You've got to take those opportunities whether you're a young player or an older player to make a statement on what type of player you are.
"It's not a final but these sorts of games have that sort of feel to them."
Longmire said playing in New Zealand was a "unique" opportunity presented to both clubs and implored his own players to also make a stand.
"It boils down to two teams wanting to win and also represent their club in the best possible way on a significant day, and that's what both teams will be trying to do tomorrow," Longmire said.
"That's the real challenge."
The Swans arrived in Wellington on Monday and trained at the Westpac Stadium on Tuesday, with Longmire claiming the swirling wind would make things "interesting".
He also said on inspection, the Swans were delighted with the "magnificent" surface of the ground.
"The wind will be a little bit tricky I'd imagine at different times ... there might be a few excuses from a couple of defenders," he said.
"I don't think there's a bad seat in the house. You're right on top of the action and you'll be able to not only see what happens but you'll be able to hear what happens, which is part of the experience of coming to see AFL football live."
St Kilda captain Nick Riewoldt admitted the Saints were "on the hunt for a win" after three losses from four games but felt they had been "thereabouts, without getting over the line".
"We're clearly playing an opposition we really respect and the way they go about it but I think we match up really well," Riewoldt said.
"Last year we had a couple of really close games with them so we're quietly confident about our chances and just looking forward to a really tough struggle out there tomorrow night."
He also said the opportunity to play on Anzac Day after watching the Magpies and Bombers face off on the historic day since 1995 was special.
"They've really had a mortgage on ... Anzac Day and represent the spirit," he said.
"To play on Anzac Day in another country for the first time in the history of the sport, it's a momentous occasion (for us).
"As a playing group, we feel really privileged to be doing that and our effort come game day is going to reflect that."
