A goal at the end of each half saw Maungakaramea beat Springfield for the first time this year and advance to the Northland reserve men's hockey grand final.
The semifinal, between last year's finalists, was a close match and started at high intensity, with little separating each team for most of the first half.
Both teams used on-field talk to up the ante in the must win match and created some good opportunities in the first half, but scrambling defence meant neither team could score.
The deadlock was eventually broken when Maungakaramea were awarded a penalty corner as the halftime whistle sounded.
The corner was played out to Maungakaramea'a advantage as Travis Baker smashed home a direct shot from the top of the circle to take a 1-0 lead into the break.
