That's also because NGHS are playing winless Keas and, based on their previous encounter, should claim victory.
All In and Outkast will have the butterflies although the latter will go on the court feeling they should be able to do the unthinkable against Otane if NGHS can.
It seems Central's campaign is over and they will play for pride.
Huias coach Rebecca Martin was thrilled with her team's start, stunning Outkast with a 14-4, 21-11 and 29-22 statements before the nail-biting finish.
"We're just good," Martin quipped when asked what lit their fuse.
She said it seemed the two-week break did her troops good but, conversely, showed they were a little underdone in their lung capacity in the final quarter.
With wing attack Abby Hall unavailable, Martin said Huias had to try different combinations so it took them a while to settle where everyone got kudos as a team.
Agreeing Otane's stumble was a "shock defeat", she said: "They are beatable. We're off to the pub now."
All In Elusive coach Charissa Barham will no doubt savour the victory after leading 15-12 in the first spell, maintaining that margin, 30-27, in the second before making their intentions clear in the third, 45-35.
However, Barham had to take Natalie Brown to hospital after an ankle injury.
HGHS coach Ina Jones, who took over from Amanda Petera four matches ago because of personal reasons, was delighted with their maiden victory.
"We had a nice win and we really needed to play as a team tonight," said Jones of the Liana Mikaele-Tu'u skippered side.
She singled out goal attack Asher Grapes for her 97 per cent shooting and goal defence Mikaele-Tu'u as they inspired HGHS to 15-11, 28-19, 40-30 in the first three quarters.
