If current polling resembles the actual results, which electorate seats would National be likely to hold on to?
Current polling suggests a swing of about 21pts (!) so not many.
National seats with majorities over 40pts last time were Hunua (47.
8), East Coast Bays (47.0), Selwyn (45.1), Rodney (43.9), Pakuranga (41.9), Taranaki-King Country (41.
8), Tāmaki (40.7)
Those just under 40pts: Clutha-Southland (39.4), Waikato (38.6), Helensville (37.
8), Botany (37.0).
Hunua has been abolished: most of it has gone to the new Port Waikato (which would presumably have a similarly mountainous notional lead), most of the rest to Papakura (which should consequentially be a bit 'safer'). Waikato is also significantly different, though the majority probably isn't hugely different.
