Bert Horner was trapped LBW by Caleb Boswell-Smith at the end of the first over, with fellow opener Joey Yovich also dismissed cheaply. But a 96-run third wicket partnership between James Thompson (63no) and Ian Page (46) helped City to a respectable 130/3 before the rest of the day was rained out at the end of the 38th over.
City now have the opportunity to put together a decent total before trying to bowl Boys High out to earn first innings points on Saturday.
The final premier grade clash saw Onerahi take control against Westech Automotives Maungakaramea at the Maungakaramea Domain with a dominant display of bowling.

The wickets were shared around with two each to Scott Robertson, Tom Herman and Fletcher Coutts and one to Rory Anders.
The Northland Cricket Reserve Grade 40 Over Competition was completely washed out.
