The minor premiers fine-tuned for finals with a 6.17 (53) to 1.3 (9) win against flag threats Clarence on Sunday.

Blues coach Angela Dickson said retaining a perfect record was not a priority for next week's crosstown derby.

"It was never a goal for us as a club to go through a year undefeated," Dickson said.

"You come out each week to win and you're happy to be undefeated at this stage.

"We are stoked we have managed to go through how we have, but hopefully we'll get out bodies right for finals.

"That's when it counts."

Launceston dominated up forward, but 23 inaccurate shots to four raised concerns.

Dickson said players have been working on those yips, but will step up goalkicking practice ahead of finals.

"It's something that has crept into our game the last four rounds. I think we're just rushing ourselves too much in front of goal," she said.

But the star playing coach was rapt to pull away from a 12-point half-time lead when she asked teammates for a lift that included 13 selfless shepherds in the third term.

"We started off a bit slow and we weren't as physical as we'd like," she said. "I put it to the girls in that second half to look after each other."

North Launceston has now lost five of its last six games on the back of a 5.5 (35) to 3.3 (21) upset against Tigers.

Coach Dean Smith feared the side was complacent after clinching a finals berth.

"I'm hoping it wasn't any of that in it - that is the cue's in the rack," he said. "I did try and tell the girls Kingborough would bring it to us."

The Bombers entered the match with a depleted backline, but Smith heaped praise on the makeshift defence.

But the club was unhappy over a Maggie Cuthbertson report in an incident that forced one of North's few true stars to come off bloodied.

Cuthbertson then was sent from the ground indefinitely, but the Bombers queried the umpire decision and kept her off for a quarter to clarify rules with senior officials.

Smith had no issues with the Tigers' attack on the ball.

"Kingborough brought the effort and tenacity," he said.

"Our intensity was good, but overall we were beaten in certain areas and some players got caught out for pace."
