Auckland headed to the semifinals without a loss to their name. With a halve to Waikato in round six following an earlier halve to Aorangi in round one, a final tie loss to Manawatu-Wanganui would have given defending champs Wellington and local hopes Northland a slim chance of making the semis.
Through nine holes the boys from the City of Sails were down, but - as they have all week - they rallied over the closing stretch to punch their ticket to the finals.
Although Waikato halved with Auckland in the morning round it was enough to give them a stress-free afternoon as the half point guaranteed their top-four place.
This was a result they surely now regret as they had to take on the top qualifiers from division two, North Harbour.
North Harbour went on to beat Waikato before causing an upset with a 3-2 win over Auckland in the final to become the 2017 Toro Interprovincial champions.
