For the hosts to have a realistic shot of reaching the semifinals and playing off for the trophy, they must follow a win over England with victory against winless Pakistan next Saturday.
"We know it's a must-win game tomorrow," Kerr said. "Essentially it's like a quarter-final so we're looking forward to it. World Cups bring pressure and we're excited."
That pressure was increased following the final-over heartbreak against South Africa on Thursday, the White Ferns' third loss in five games.
Given two of those setbacks have been by losing margins of three runs and two wickets, New Zealand are likely to feel aggrieved if their contention at this tournament does come to a premature end.
But below pacesetters Australia and South Africa, the next five teams have all displayed the capability to beat one another, meaning fine margins will determine the semifinalists. And in pressurised environments at Seddon Park on Thursday and in their opener against the West Indies, the White Ferns have been deficient when it mattered.
Which will matter much less if they win these next two games, but Kerr knows life won't get any easier against a defending champion scrapping for their own lives, even if it took England four matches to register their first victory.
"They've got a few world-class cricketers," Kerr said. "Nat Sciver is one of the best allrounders in the game and Katherine Brunt is a very experienced campaigner, then you've got Heather Knight and Sophie Ecclestone, who's a real key for them with the ball.
"But I think if we just worry about what we can do well and how we want to go about our business, that's the most important thing."
Kerr was looking forward to seeing Eden Park tomorrow from a less lofty perch, with the White Ferns having not played an ODI at the venue since 2000, before the 21-year-old was born.
The stadium proved a favourable host when the Black Caps last played a World Cup match there and, although the stakes aren't as high as that 2015 semifinal, the White Ferns are desperate to make more good memories tomorrow.
"We just want to give ourselves the best possible chance to get to the playoff stages," Kerr said. "There's been a lot of good sporting moments here at Eden Park so hopefully we can add to that tomorrow."
