"It's something that as you get older it gets easier to do, because if you hold on to games like that they can certainly chew away at you," the skipper said.
"Obviously you want to take key [lessons] out of a loss like that, but you also want to move on because the longer you dwell on it the more it sucks out of you."
A 141-run thumping will do that to a player, though Devine stressed the strength of an opposition who had been "under a huge amount of pressure" after 30 overs.
That pressure was soon alleviated with some loose death bowling, which would be one lesson the White Ferns took from the Basin Reserve. And if Devine was willing to cast her mind back to the last time New Zealand faced South Africa, plenty more would be found.
In that series on these shores in 2020 - the only time the sides have played in the last five years - South Africa comfortably chased down three targets to complete a sweep.
New Zealand's bowlers took only nine wickets to the visitors' 29, providing an early warning about a South African attack that has shone at this tournament.
"They're an absolutely quality side and we've seen that by their performances so far," Devine said. "You look at them with the ball and they've got strengths all the way through their lineup.
"But we also know that we've got some great matchups and great challenges ahead. We know when we play our best cricket we can beat anyone."
That, the White Ferns hope, will extend even to Australia, though they would be wise to avoid fourth place and postpone any rematch against the presumptive top qualifiers until the trophy is on the line.
England's four-wicket win over India yesterday might have helped that cause, with New Zealand set to play the previously winless English on Sunday.
Defeat today wouldn't be fatal, but two wins this week would all but guarantee the chance to make some happier memories deeper into the tournament.
"The girls are fizzed," Devine said. "This is getting to the pointy end of the tournament now and we know the situation that lays ahead of us.
"We know we need to win and that provides some challenges and some pressure, but it's also something that we want to step toward."
