Poverty Bay overcame Mid Canterbury 33-26, getting payback for a 22-19 away loss to the same team on October 23.
But the biggest prize in any Heartland campaign is the Meads Cup, and after years of heartbreak when being upset in home playoffs, South Canterbury finally claimed the prize with a comfortable 35-16 win over Thames Valley in Timaru.
They completed only the third unbeaten season in Heartland history, although the 2008 and 2016 Whanganui sides played in competitions with semifinals.
