Heather Knight's team ended their three-match losing run with a four-wicket victory against India last Wednesday.
Despite this, the defending champions still face an uphill battle for qualification, starting with a crunch tie against New Zealand.
The tournament hosts have endured a similarly mixed start, having won two and lost three of their first five contests.
With both teams in-need of a victory, Saturday's match in Auckland is finely poised.
Speaking ahead of the game, Shrubsole admitted that her side are certainly not short on motivation.
She said: "We want to win every game of cricket that we play, we're here representing England and we have a huge amount of pride in that and we're here to win every game that we play.
"So yes we're obviously motivated but I wouldn't say we're necessarily more motivated than the three games that we lost and the three games that we're about to play.
"We're motivated by wanting to put some things right that we feel like we haven't achieved in this tournament so far and everyone will individually have their own motivation.
"So I guess we're wanting to come out here and win and that just goes without saying, that's how we approach every single game and I guess it's about us wanting to give a true reflection of ourselves as a team that we feel like we haven't done at times during this tournament."
