A 28-run win over Manawatū on Friday afternoon proved to be a key result, with the hosts finishing second on the ladder with three wins from their four games.
Hawke's Bay picked up where they left off on Saturday morning by posting another big first innings total of 179/6 against Taranaki.
Opening batsmen Angus Schaw (40 off 25) and Christian Leopard (80 off 49) laid the foundation for what would eventually be a 26-run win.
The Hawke's Bay bowlers picked up regular wickets throughout Taranaki's chase, with Schaw, Todd Watson and Toby Findlay each nabbing two.
On Saturday afternoon, Hawke's Bay were put in to bowl first for the first time in the competition against Horowhenua-Kāpiti.
The change didn't slow them down though – Horowhenua-Kāpiti only made 99/8 in their 20 overs.
Watson picked up the best bowling figures with three wickets off his four overs, conceding just 10 runs.
He also helped steer Hawke's Bay home with the bat, finishing the run chase off with Dominic Thompson to secure a six-wicket victory.
