From my observation in the last couple of years, playing against Waimak at Kendall park is starkly different to playing Waimak at Manpower Oval. The Rangiora based team is loaded with poms. I actually laughed when I read that comment.
It wouldn't be much of an issue for Waimak to seperate would it? Apart from maybe the Div 1 side would likely be split in two..
