The league planned to use the regular starting times for games during finals but has been forced to change on Sunday due to the bottom court at Friendly Societies' Park.

"The court is suitable to play on when it is raining or when it is fully dry," league chief executive officer Stephen Soulsby said.

"The issue in relation to the bottom court arises during the period where the court is drying out, which causes players to slip."

Clubs voted at a league netball forum earlier this month that regardless of the weather, only the top court should be used in a bid to avoid serious injury and to ensure a safe playing surface is provided.

The 13 and under match will start at 9am followed by 15 and unders at 10am, 17 and unders at 11am, A2 at 12pm, A1 at 1pm and seniors at 2pm.

Gates for the first three weeks of finals will open at 8am.

On grand final day, gates will open at 7.30am.
