Edit: My wishful thinking brain overrode my math brain.....Op+Gn only have 23 (16+7). No path for NOG government on current numbers. Would have to change a lot with the specials coming in.
ON current numbers; Opportunity + Green have 25 seats; National has 42.
That gives 67; a slim 1 seat majority.
I know it is very unlikely; it is the same one seat majority; that National, Act and NZF have.
But the specials have a good chance of shifting to the left, they traditionally do, which may increase the OpGn share.
That and the colours work out so nicely; National with the blue, Opportunity in the middle with teal and Greens with green.
They could be the chromatically satisfying coalition.
