But normally it would be New Zealand vs New Caledonia and then New Caledonia vs Fiji in one window; Fiji vs New Zealand and New Caledonia vs New Zealand the next window, etc. I'm not sure of any confederations that have group matches twice in a row between two teams? CONCACAF doesn't do it, neither does UEFA, CAF, AFC or CONMEBOL. It's just OFC that does it.
It's gonna be agonising if we're 5 points ahead of one of them in the last window in June 2017 and we can only watch them because we've played all our matches and they've still got a double-header.
