Hora Hora have impressed after a slow start, but have lost two of their last three and will want to keep adding to their lead over Kamo.
OBM continue to stretch their lead with ease, coasting past second-placed Mid Northern last week and sending a message to the rest of the competition.
Mid Northern travel to take on Otamatea, with both sides wanting to make up for resounding round-10 defeats.
Mid Northern have been strong all season, so it's hard to imagine them being behind the eight ball for long.
Otamatea remain jammed in the tight middle of the table tussle. Just five points separates ninth-placed Otamatea from Kamo in fifth. A win here would elevate their shrinking odds of making the top four.
The final match of the round gives Mid Western an opportunity to break their 2017 duck when they face Waipu at home.
