Mount Maunganui Sports and Whakarewarewa produced 80 minutes of rugby at Blake Park on Saturday worthy of any grand final stage.
Undefeated Mount Maunganui came back from trailing 21-13 with 10 minutes to play to snatch a thrilling 24-21 victory well into injury time in captain Chris Elvin's 200th match.
The skill level and intensity was a step up from the preceding three rounds as some of the Bay's best players locked horns in a pulsating game played in front of Steamers head coach Clayton McMillan.
The hero for the green and golds was first-five Ngatai Kingi, making his first start of the season with regular pivot Pera Gibbs injured. Kingi kicked two late penalties under pressure to snatch the win, with the decisive goal a beauty from near touch 30 metres out.
Kingi is well regarded in Bay of Plenty rugby circles as one of the talented crop of young 10s coming through the development system and before this season played his rugby for Rangiuru.
