But it was also the impetus for parties like New Zealand First and Act, appealing to those who yearned for more simplistic and supposedly equalitarian concepts - a fairness for all. And whatever you might say about Winston Peters, he's not an amateur. He's about as professional as you can get in this game.
But by far the greatest staying power is popularity, as John Key has ably demonstrated.
You can survive for a while, a good while, with a minority liking you, especially if you become a minor celebrity and make a lot of noise, but if you don't capture an electorate you're at risk of never achieving the 5 per cent threshold needed under the MMP system.
Kim Dotcom is an excellent demonstration that notoriety, noise and money counts for very little with the voter. The Conservatives never got that 5 per cent and, without a foothold in Parliament, they were amateurs doomed to running out of steam.
Their politics, which I always felt were a bit intolerant, had a certain "conservative" appeal.
I would have thought by now that most political parties would know this country is tolerant. Appealing to the intolerant will earn you some points, because these people are out there, and amateur politicians can get them on board.
But a professional politician appeals to all of New Zealand.
