The surprises kept coming with Southern too strong for joint defending champions University at Logan Park.
The Magpies dominated the forward exchanges to win 30-15. University made a lot of mistakes, though.
Harbour prevailed 20-15 against Kaikorai in a tight encounter at Bishopscourt. The old warhorse Charles Elton produced another solid performance for the Hawks.
And on Friday night Green Island dispatched Alhambra-Union 46-18 at Forsyth Barr Stadium.
