Truro City secured fourth place in the National League South after a goalless draw at Havant and Waterlooville.
The point put the White Tigers four ahead of fifth-placed Whitehawk ahead of their final game of their season at home to Wealdstone on Saturday.
It also ensured they will face Maidstone United in a two-legged play-off semi-final.
Steve Tully's men will be at home for the first leg on Wednesday 4 May before travelling to Kent four days later.
Truro are bidding for a second successive promotion after winning the Southern Premier League play-offs last season.
