The marriage between United Future and Outdoor Recreation New Zealand seems to have ended in divorce, with Outdoor Recreation citing irreconcilable differences. Apparantly, they didn't like being proselytised at by Christian fundamentalists.
The merger was a marriage of convenience anyway, driven primarily by MMP's undemocratic threshold rather than any real common ground between the parties. At the same time, it also seemed to be part of a project by Peter Dunne to broaden his party's base away from being a purely religious party towards the middle of the road party he'd always wanted. Outdoor Recreation's departure basically brings that project to an end, and probably means that United Future is likely to remain a small party for the forseeable future.
