Top qualifier Wanganui will host Thames Valley in the Meads Cup semifinals in the Mitre 10 Heartland competition next weekend while top qualifier Horowhenua Kapiti will host Mid Canterbury in the Lochore Cup.
The final placings for the Lochore Cup were affected by West Coast losing six competition points due to an eligibility breach to slip back to 16 points, allowing Mid Canterbury to step up into the semifinals.
Wanganui beat Horowhenua Kapiti 57-27 in the final round robin games on Saturday.
In the other Meads Cup semifinal South Canterbury, who beat Thames Valley 33-24 in Timaru will play King Country who had a 31-29 win over Mid Canterbury in Ashburton on Saturday.
North Otago beat Wairarapa Bush 24-0 and by failing to score a bonus point try they ended up having to return to Masterton for the second Lochore Cup semifinal.
