Adams commended his team on their counter-attack and use of pace in the first half, but he advised the girls at halftime to keep the pressure on their opposition.
"I was trying to emphasise that the next goal was going to be important because 2-0 is always a tricky scoreline," he said.
"I don't think we came out with the right attitude and intensity in the second half and the start of the last quarter, where we needed to make sure we put them away and we just about didn't do it."
Trailing by nine points to league leaders Springfield, Adams was happy with his team's progression looking ahead to the knockout stages.
"This is my third year coaching and we have struggled until the knockout games when we tend to get everything together, but this year we seem to be more than competitive which is pretty pleasing."
In the round's other game, Springfield overcame Hikurangi, 2-0. In the premier men's hockey competition, Mangapai beat Whangārei Boys' High School, 4-2 and Springfield beat Bream Bay United 2-0.
