“It’s a big game for both teams.
“Our aim at the start of the season was to win the competition.
“A win tomorrow keeps us in the hunt, especially with a game against Napier City Rovers here in three weeks. But we need to beat Port Hill.”
Adams said the decision to switch Mal Scammell from centreback to a defensive midfield role, with Kieran Venema moving into the back four, had been a success.
“It’s been a good move for both players and for the team, so we’ll stick with that for this game,” he said.
Gisborne Thistle’s home game against Hastings Western Rangers has been postponed because all council grounds have been closed for the weekend.
Thistle coach Garrett Blair said the game was now likely to be played at Childers Road Reserve on June 23.
“That’s a cup-round weekend and neither team would be playing otherwise,” Blair said.
“That means we’d both be free for a catch-up game on the Saturday.”
