Harbour routed Southern 59-10 at Bathgate Park. The final margin would have been much more but the Hawks converted just two of their 11 tries.
University dispatched Alhambra Union 47-0 at the University of Otago Oval in another one-sided encounter. Highlanders Josh Dickson, Matt Faddes and Fletcher Smith had a big impact on the game for the students.
It was much closer at Peter Johnstone Park. Taieri trailed Dunedin 11-5 at the break but had too much class out wide and pulled away to win 29-18.
In the other game, Kaikorai blitzed Zingari-Richmond 59-6 at Bishopscourt.
