"We kind of need it," she said. "We'll take anyone who wants to turn up wearing pink on the day."
Havelock have never beaten Napier Tech during their three seasons as a club and coaches Cornwall and former Black Stick Emily Gaddum admit they're underdogs heading into the final.
"We'll only beat them by playing our style of hockey, which is considered and structured," Cornwall said.
"We can beat them, but we don't expect or anticipate that to come easily. They are a class side, and we have a lot of respect for them."
Havelock made this season's final after a confidence boosting 4-2 win over Bay Independent Ferns last weekend.
Gaddum said the victory was a "solid team effort with some great goals".
The pink and white striped side have netted over 50 goals this season - a similar attacking tally to Napier Tech who've scored 59 goals, but only conceded seven.
Napier Tech made yet another final by beating Akina Rovers Horsefield 4-0 in their semifinal. Tech have won the past two leagues titles, beating Havelock in the 2018 and 2019 division finals.
The Holly Varcoe-coached side showed their pace and dominance across the pitch in last weekend's match.
Varcoe believes her squad still haven't reached their full potential.
"It will be a bloody scary thing for our opposition if we pull that off this weekend," she said.
Whilst Varcoe and her squad have done their research on Havelock's strengths and weaknesses, they are preparing for Saturday's match by concentrating on their own game.
"Our focus is 100 per cent on our own game plan, what we need to do to win, and win well," she said.
"We are always looking to improve on performances and the final will be no exception. My girls have got this."
The women's division 1 hockey final will be followed by the men's division 1 final on Saturday, where Bay Independent 1 will face off against club-rivals Bay Independent 2 at 4.15pm.
