Another goal followed before halftime to extend the lead to 3-1, which quickly grew as Otumoetai ran the Pukekohe side ragged while keeping them scoreless in the second half.
In the end, the competition leaders prevailed 6-1 - registering their 50th goal of the season to increase their positive goal differential to 34.
Gilmer was again strong at the back. He communicated effectively to marshal his troops and fired pinpoint passes past the visitors' attempted defensive screens, while the precision of Fowler and the pace of Harris proved far too much for the second Pukekohe team in as many weeks.
Otumoetai travel to Ngatea to play Valley United next weekend while second-placed CMS Mount will host Onewhero Pukekohe at the Tauranga Hockey Centre.
