"That competition resumes next Saturday with the final game of round robin against St Peter's before we go into the top four competition with Palmerston North Girls' High and the two Manukura teams. The top four is pretty much knockout competition," Murphy said.
WHS finished third in the Manawatu competition last season.
"That's the highest we've very reached in that competition, so we have a very realistic chance of bettering that this year."
Meanwhile, multiple Netball Whanganui champions Wanganui Car Centre Kaierau A1 also had a comfortable 55-24 win over Kaierau A2 on Monday in a match that allowed coach Walter Edmonds to test combinations before his team's clash with WHS next week.
"It was a comfortable win against our A2 side and a big score, but it did allow us to try different combinations that will work best for us against WHS next week," Edmonds said.
"The game next week will be a big one and we need to be ready. I'm quite happy with our team effort on Monday."
Mere Te Aroha had the bye on Monday.
