Saturday's State League grand final will be a second straight all-Northern affair at the Silverdome with Cavs also edging out their neighbours 47-44 to set up a 19s-and-under decider against minor premiers Cripps.

"It's great for Northern netball that we will have three-quarters of the grand final teams from up here," Roden said after both Launceston teams progressed from their semis on Saturday.

Cavaliers will be looking to repeat their grand final victory against the Hawks last year while the team co-coached by Ruth Tuohy and Kellie Woolnough is eagerly anticipating a fifth straight decider.

Netball Tasmania has confirmed both matches will take place in Launceston on Saturday with the 19s at midday and the opens at 2.30pm.

The Northern neighbours have again dominated their rivals in this year's rescheduled competition.

Hawks have not looked back since starting with a one-goal win over Arrows way back in March, going through the season undefeated to finish minor premiers.

Meanwhile, Cavaliers' only losses came to their Silverdome co-tenants. Hawks won the delayed round three clash by four goals and in round 10 by 22.

Cripps came within three goals in round seven while Kingston kept the semi close before bowing out 61-50.

Hawks had earlier seen off fourth-placed Cripps 70-49 after a nervy start had the sides level just before the main break.
