The Wellington Blaze have comfortably beaten the Auckland Hearts to set up a Super Smash finale against the Canterbury Magicians.
And the reward is a home final against the top of the table Magicians, on Saturday, at the Basin Reserve.
The Blaze bounced back from a disappointing loss to Auckland last week, at the same venue - Eden Park's outer oval.
Amelia Kerr was the star for the defending champions, blazing an unbeaten half-century (54) as Wellington reached 150/6 from their 20 overs.
That target would prove more than enough, as the Hearts limped to 115/7 as the Blaze completed a 36-run-win.
Wellington got off to a fast start after winning the toss and batting through skipper Maddy Green and Blackcaps star Sophie Devine, smashing 45 form the first six overs.
Step up White Fern to be, Fran Jonas, who dismissed her national captain with the first ball she bowled to Devine, trapping her in front for 33.
But the batting wobbles that plagued the Blaze last week disappeared, with Green (32) and Kerr ensuring a more than competitive target would be achieved.
Jonas was the star with the ball, finishing an impressive spell of 2/23 from her four overs.
The Hearts never looked like challenging 151, and despite a neat partnership between Katie Perkins (46) and Bella Armstrong (33), the brakes never came off the run-chase.
Kerr added 2/16 to her impressive showing with the bat, to complete a dominant individual performance.
