The acceptance of, and susceptibility to, such tactics by voters leaves our politics all the poorer. We must hope that this distressing disregard for principle will not be carried into government.
The collapse of the Maori party suggests that Maori voters have realised that the issues that particularly matter to Maori cannot be safely entrusted to a government that sees its priority as serving the interests of business. A large number of similarly placed Pakeha voters have been much slower on the uptake.
Labour, and Labour's Maori MPs, must now show that they are worthy of the trust reposed in them.
The Greens held on, surviving mistakes of their own making, and remain in play as a possible coalition partner in a progressive government. They continue to bring a valuable dimension to our politics.
As always seemed likely, the final decision as to who will form the next government rests with Winston Peters and his New Zealand First MPs.
The election shows that there is an appetite and a momentum for change that is likely to grow rather than subside. "More of the same" is not sufficiently inspiring to claim new adherents.
We have a real chance to make a fresh start. And remember that, in MMP politics, votes for the largest party carry no additional weight. What matters is whether a majority exists in parliament.
The chance arises to bring fresh minds to bear on old and neglected issues. Rather than act as a mere adjunct to an existing administration, Winston could play an important role, as an elder statesman in, and foundation member of, a new government - one that catches the incoming tide.
