The bar is each candidate's chance of winning the seat. A candidate who loses the seat can still get into Parliament on their party's list; the list chance is how often that happens.

How close

In our central forecast, National leads Labour by about 20 points, so a swing of 9.9 points to Labour would tie it.

The lead is the gap between the top two candidates in our central forecast. The typical winning margin is the other way of looking at it: in a typical simulation the winner is ahead by this much, whoever wins. The range covers eight in ten simulations. The rating and how close the seat is come from the favourite's chance across the simulations: a toss-up under 60%, leans under 75%, likely under 95%, safe from 95%.

Different from the country?
