I’ve previously blogged on whether specials may change any allocation of List MPs. The other question is whether any seats held by narrow majorities could change due to specials. The answer is yes, but unlikely.
The most marginal seat is New Plymouth – Jonathan Young got 48.6% of the vote to 47.6% for Harry Duynhoven. There were 32,029 valid votes. There are 2,351 known specials for the seat and we estimate 1/70th of the 32,000 overseas specials, so the numebr of specials is predicted to be 2,808.
The specials would have to be 6.1% better for Labour and worse for National for Harry to win. Or in other words they would need to go Harry’s way 53.7% to 42.5%.
In Auckland Central Nikki Kaye beat Judith Tizard by 1,181 votes. However there are a large 6,420 specials plus overseas votes. Niiki beat Judith 43.0% to 38.8%. Judith would need to win the specials 49.5% to 32.3% to close the gap.
New Plymouth looks to be the only seat which could seriously change, and even that isn’t very likely.
