The All Whites face Belgium in Vancouver on Saturday in their final group stage match with their World Cup campaign hanging in the balance.
New Zealand must win to advance from Group G after drawing with Iran and losing to Egypt in their opening two fixtures. The team sits at the bottom of the group with one point.
All Whites coach Darren Bazeley acknowledged the precarious position but emphasised the opportunity still available to his squad.
"It still hurts that we've only got the one point after the performances," Bazeley said. "But that one point did mean that we go to the end of the tournament in the group stage knowing a win and you go through, we've given ourselves that chance."
Bazeley said the match represents the knockout football New Zealand came to the tournament seeking. "We came for knockout football and, in effect, we've got that. [It's] come around earlier, but now we're playing knockout football."
The coach made clear the margin for error against Belgium is non-existent.
"In this game, we need to be flawless, we can't make a mistake," Bazeley said.
He outlined the dual challenge facing his side. "I think it's going to have to be a perfect performance in and out of possession. We're going to have to be brave, courageous on the ball and, again, somebody's going to have to take a moment of quality and score a goal or two or three."
Victory would represent New Zealand's first win against a top-10 ranked team.
New Zealand has occupied a position in the 80s in FIFA's world rankings from late 2024 onwards, a period covering most of Bazeley's time as coach.
Bazeley said the squad believes they are better than their ranking indicates, attributing the position to New Zealand's lack of competitive fixtures that would generate higher FIFA ranking points.
Saturday's match in Vancouver will determine whether New Zealand progresses to the knockout stages or exits the World Cup. A draw or loss ends the campaign; only victory keeps the All Whites in the tournament.
