Now the nominal list by itself is only a partial picture. One has to look at the “Effective List” to work out who may come in when. The Effective List is the likely List MPs, after taking account of those who will win their electorate seats.
Now let us assume the 29 candidates who already are Electorate MPs will retain their seats. Let us also assume Amy Adams will win Selwyn (replaces Rakaia which is ultra safe National) and Simon Bridges will win Selwyn Tauranga (based on Colmar Brunton poll).
Which other candidates may win their seats? Well there are no public polls in those seats, but I did calculate an electoral pendulum back in May which calculates what seats would fall on a standard swing. The swing never is standard of course, so these are not predictions – just an assumption on the best public data there is. The One News Colmar Brunton is the only poll which asks how people will vote on the electorate vote, and in July it had a gap between National and Labour of 15%. Now on the electoral pendulum this would see the following seats picked up:
- Taupo (Louise Upston)
- Rotorua (Todd McClay)
- Otaki (Nathan Guy)
- Hamilton West (Tim Macindoe)
- West Coast-Tasman (Chris Auchinvole)
- Palmerston North (Malcolm Plimmer)
- Auckland Central (Nikki Kaye)
- New Plymouth (Jonathan Young)
So assuming National wins 39 electorate seats, you then ask how many seats National would win overall based on its party vote. Now we do not know what vote National will get, but let us go off the date and time weighted average of recent polls at curiablog which has National at 50.9%. One also then needs to work out what National’s share of the effective vote is, eliminating the parties that fail to qualify for representation. At present the minnows get 1.1% and NZ First 4.4% which means 5.5% is wasted. National’s effective vote is 50.9%/(100% – 5.5%) = 53.9%. This would get National 64 MPs in total and on the assumptions above 39 electorate MPs, and 25 list MPs.
Now NZ First is close to 5% and if they make it, that will have an effect, so in the table below I’ll do two columns. The first showing what percentage of the party vote is needed for a candidate to come in off the list if NZ First do not make it (and wasted vote is 5.5%) and if NZ First do make it (and wasted vote is say 1% as it was in 2005).
Now once again this is not a prediction. This is a scenario based on publicly available polls. I am not saying National will win 65 seats, nor am I predicting what electorate National will win. I am reflecting the current public poll data.
Now let us look at some of the individual winners, before we look at the overall possible Caucus.
Caucus are all in the top 50, which will be pleasing to them. Unless National drops below 43% (if NZ First do not make it) or 45% (if NZ First do make it), all MPs will be returned.
Of the 2005 intake, the top ranked are Chris Finlayson and Tim Groser who are ranked 14 and 15, which is no 2 and no 3 on the effective list. Next is Tau Henare at 26 (7), Jonathan Coleman 29 and Kate Wilkinson at 30 (8).
Of the new candidates, Steven Joyce is in a league of his own at no 16 (4). Then four new candidates are placed in the 30s, above some MPs and guaranteed of entry so long as National polls as well as last time. They are Sam Lotu-Iiga, Hekia Parata, Melissa Lee and Kanwal JS Bakshi.
After the top 50, you have seven mainly relatively young candidates in Simon Bridges, Amy Adams, Louise Upston, Todd McClay, Tim Macindoe, Aaron Gilmore and Nikki Kaye. On the standaed pendulum, most of them will win their seats and not need the list place.
After them making up the 50s is Cam Calder, Conway Powell and Stephen Franks, all in winnable places. In fact few positions are not winnable on current polls (which is why six extra list only candidates were added onto the bottom of the list as an insurance policy in case National got more than 67 MPs. The Fairfax poll yesterday would have it receive 70 MPs. Roy Morgan however would have only 58 MPs.
So what does the next National caucus look like? Well on the current public polls average, it would be a caucus of 65 with:
- 17 female MPs (26%)
- 13 MPs under 40 (20%)
- 7 Maori MPs (11%)
- 1 Pacific MP
- 3 Asian MPs
What if things tighten up? What would it be if NZ First do make it, and National gets say 47%? That would be a caucus of 57 with:
- 17 female MPs (29%)
- 11 MPs under 40 (19%)
- 6 Maori MPs (10%)
- 1 Pacific MP
- 3 Asian MPs
Under either scenario it will be a relatively diverse caucus, with a lot of new talent coming through.
