The National Party has had a month to get over the disappointment of winning the election but losing the partners it needed to continue governing. It is in an unprecedented position in New Zealand's post-war politics — having more seats in Parliament than the party leading the Government. This outcome poses new challenges for the Opposition as much as for the Government.
For the moment, the Opposition's challenge is harder. The Government has things it promised to do and can get on with doing them, knowing the public will suspend judgment until a new Government has had a chance to show its character and its competence by making some decisions.
An Opposition, though, has not much to do except wait for any weaknesses in the Government to be found. This normally suits the party in Opposition well enough since it has normally suffered electoral rejection after a period in power and needs the time to lick its wounds and regroup.
That is not National's situation now. It has come back to Parliament with a much higher popular vote than any other party in the House and many of those voters probably feel as cheated as National that they are no longer governed by the party that won the most seats. But as National has responsibly told them, that is the electoral system the country has chosen. It is too soon to say whether the system will be discredited by the coalition it has put in power.
In the meantime, National has to make an important tactical choice: should it act like a normal negative Opposition or does its unusual strength give it a better option. So far it is acting like a normal Opposition, gleefully catching the Government napping over the numbers it needed to elected Parliament's Speaker and deluging the new ministers with no fewer than 6000 written questions over the month.
