"There are just more strong schools in the Auckland competition, and it would be great if we all played together [for the full season]," she said.
"The girls had worked really hard in 2014, and a large part of our success was down to the fact that we had played Super City for all of last year."
Sharland said that although her team "bombed" at the nationals, they were not using the change of format as an excuse for the relative failure. After all, they won the Super City competition and racked up a winning streak of more than 20 matches before losing in the nationals to St Cuthbert's.
But Sharland argues they are able to develop their players better and faster with a higher level of hockey than they receive in North Harbour at the start of the season. Rangitoto College, Carmel and Kristin were the other North Harbour schools to compete in the top tier of the Super City in 2014.
North Harbour Hockey chief executive Riki Burgess says he can understand Westlake's stance, but has to maintain the integrity of North Harbour schools hockey competition.
"It was about us working with College Sport on a format that suited all schools. It's hard for those big schools like Westlake Girls' at times because they are dominant in several sports. But we are hoping to get to a happy medium of meeting their needs and the wider hockey community's needs."
Westlake Boys' High was the only North Harbour boys' school to compete in the 2013 Super City competition, which they won. They lost the final of the 2014 competition to King's, which they had beaten 12 months earlier in the decider.
College Sport takes a break for the school holidays, and will return on Wednesday, October 22.
