Their captain Eliza Stephens said Waimana gave them a tough run.
"When we arrived before the game, Waimana were already here at our home turf and that was quite intimidating in itself to see an away team here before we got here," she said. "So when I saw that coming down the drive I knew they were not here to muck around."
She said there was a feeling of relief after the game, knowing they had made the final.
However, Stephens said it would be daunting going into the grand final with their undefeated record on the line.
"That is quite a scary place for us, you know.
"I mean who wants to go unbeaten then lose in the final," she said.
"We always reflect on last year how we got to the final and then we lost [to Arataki], so those feelings keep getting brought back and that's where we dig deep from, we don't want that hurt again."
Stephens said they would like to hold the final this coming Saturday at Bellvue Rd if possible, otherwise they would have to play the final on Sunday.
