A referendum on MMP is too serious a matter to be settled by ad-lib on talkback radio
The Prime Minister, Christopher Luxon, has confirmed that he told a talkback audience he would hold a referendum on the mixed member proportional system if re-elected, and has since said he felt sorry for the caucus colleagues who learned of the commitment the same way the rest of the country did. Both facts belong together. A promise to reopen the electoral system under which every member of Parliament now sits was made in public before it was made in Cabinet, and before it was made to the very colleagues whose seats and party arrangements it would touch.
What is at stake here is not only MMP, which New Zealanders chose in 1993 after years of formal review and two referendums, and which has bedded in as the accepted method by which this country forms its governments. What is also at stake is the discipline by which government business is conducted at all. Cabinet government depends on collective decision and shared responsibility; a coalition depends on partners who can trust that large commitments will not arrive as a surprise on the car radio. A Prime Minister who wishes to reconsider the electoral system is entitled to that view. A Prime Minister who commits the Government to it without consulting Cabinet or coalition partners has confused a personal opinion with an announced policy.
There is a case to be made for the Prime Minister's instinct, and this newspaper will make it plainly. Direct, unscripted engagement with the public has its uses, and a leader who will not say what he thinks when asked is not necessarily to be admired for his caution. It may also be true that MMP, three decades old, deserves periodic scrutiny, and that raising the question is not itself illegitimate. But the manner chosen here forecloses the very deliberation that any change to how New Zealanders elect their Parliament would require. A referendum promise made on air cannot be unmade on air, and the caucus now finds itself defending a position it did not choose and was not asked to test.
- Set out to caucus and coalition partners, without further delay, exactly what process the Government intends to follow before any referendum is confirmed.
- Refer the question of electoral reform to a proper independent review, of the kind the 1993 change itself was built on, rather than treat it as settled by talkback.
- Make no further constitutional commitments on air that Cabinet has not first agreed to.
