The Wellington Firebirds and Blaze have capped off their Super Smash seasons by beating the Auckland Aces and Hearts in their respective finals at the Basin Reserve.
The Firebirds men claimed a win, thanks to 49 from the competition's top run-scorer Devon Conway and three wickets from Logan van Beek.
Batting first, the Firebirds set a modest 168/7, with Conway top-scoring.
Blackcaps opener Martin Guptill scored a gallant 60 in reply, but his magnificent innings came to an end, thanks to a spectacular piece of fielding on the boundary to dismiss him from van Beek.
The Aces managed to take the match to the final over, but fell 22 runs short, handing the Firebirds their first title since 2017.
Recalled Blackcaps Hamish Bennett was the pick of the bowlers for the Firebirds, claiming 3/34 off his four overs.
Earlier, in a rain-shortened women's final, new White Ferns captain Sophie Devine smacked a quick half-century to blast the Wellington Blaze to their third-straight title and put the finishing touches on an unbeaten season.
Devine scored 54 of the hosts' 81 runs in their innings, which was reduced to seven overs each.
The 30-year-old hit five sixes and four fours in her match-winning knock.
In reply, the Auckland Hearts managed just 45/4 to lose by 36 runs.
