The defending champions Canterbury will host Hawke's Bay in Christchurch next week while Wellington host Southland following Saturday night's penultimate round robin game, which saw Auckland end Waikato's hopes of a semi-final place in the provincial rugby competition.
Auckland beat the hosts 26-18 in Hamilton after leading 13-11 at half-time.
Waikato were the only team left that could've taken fourth place off Hawke's Bay with a four-try bonus point victory.
Second-placed Wellington have secured the other home semi after scraping past Tasman 22-14 in Blenheim, the win meaning the Lions will host the other semi-final against third-placed Southland.
In the afternoon game Manawatu have thrashed North Harbour 42-16 at Palmerston North.
