So far, McInnes felt captain Steph Donnelly, Georgia Miller, Bridget Johnson and Hayley Maunder had stepped up for the Northland team.
However, with Northland club hockey coming to the business end of the season, McInnes jokingly hoped the youngsters' form would not be around when they played her Hikurangi club team.
So far, the team's results have been a 2-1 loss to Central, a 3-0 loss to Auckland, and a 2-0 loss to North Harbour.
The women's only goal scorer in the competition so far is Ella-Rose Kini.
Meanwhile, the Northland men's under-18 team have had a similar story for their tournament.
They too have had no wins from their three games - losing 8-0 to Midlands, 5-1 to Auckland, and 5-2 to Central.
Scoring goals for the men's team so far have been Chantz Wilson-Harding, Hamish McKechnie and Harry Lamb.
Today the women's team play Capital at 11am, before playing Southern tomorrow at 9.30am. Depending on those results, and the other teams', Northland will again play on Saturday to determine their final placing.
The men face Southern at 11.30am today and take on North Harbour at 9am tomorrow to round out their pool play.
