Chasing the Xenophobic Vote?

One piece of evidence perhaps consistent with that that Labour's "dey terk yer house" xenophobic housing policy was in pursuit of votes that otherwise go to NZ First: shortly after Shearer announced it, traders at iPredict downgraded Winston's chances of returning to Parliament.

It's hardly conclusive: it's a pretty thin market. But traders reckoned that Peter's chances of returning to Parliament dropped from about 85% to about 62% on Sunday, 28 July.

And here's the strange part. Q&A, the TVNZ Sunday newsmagazine programme on which Shearer made his announcement, airs at 8:50 a.m. I'm not sure at what time after 8:50 Shearer made his announcement, but the trading on NZ First started at 7:19 Sunday morning, when what looks like a single trader pushed Peters to a 30% chance of returning to Parliament. That returned to 68% later in the day, and since eroded to 54%. So either:

• iPredict's time stamps are a couple hours out;
• Somebody knew what Shearer was going to announce and predicted that it would hurt NZ First - that somebody would most likely be in Labour as the announcement only came on Q&A;
• Something else served as shock to NZ First prices early Sunday morning and that move then stuck, perhaps because of the Shearer announcement, perhaps because of something else.

I don't think iPredict's time stamps are out. I shorted one "NZ First not to be in Parliament after next election" share at 10:35 to check it, and it's reporting that that's the last trade time. So pick one of the other two. 

If somebody in the Labour camp put a few bucks against Peters in anticipation of Shearer's Q&A appearance, that would be interesting.

Thanks to @JohnnySharland for the pointer.
