A referendum on MMP is too large a matter to be settled by a promise made on talkback radio
The Prime Minister, Christopher Luxon, told a talkback audience that he would hold a referendum on the MMP electoral system if his Government is returned. He has since said he felt sorry for the caucus colleagues who learned of this commitment the same way the public did. That admission is candid. It does not make the commitment sound.
Electoral law is not a small matter, and the manner of its making counts as much as its content. New Zealand adopted MMP after a royal commission, two referenda and years of public argument. Whatever the merits of revisiting that system, and this newspaper does not pretend the merits are nil, a change of this order deserves at least the same care that went into its making. A promise given to a radio host, before Cabinet has agreed a position and before caucus has been told, is not a policy. It is a hostage to fortune, and the country's electoral arrangements are no place to take such risks.
The strongest case for the Prime Minister's position is that MMP has genuine, long-argued flaws, among them the size of governing arrangements it can produce and the standing of list members who answer to no electorate. A government that believes those flaws serious enough to warrant a referendum is entitled to say so. But entitlement to a view is not the same as licence to bind a future Parliament to a timetable settled in a radio studio. The Electoral Commission exists for exactly this kind of question, and its processes, however slower than a talkback answer, carry a legitimacy that an offhand promise cannot supply.
The Minister of Justice, Paul Goldsmith, carries responsibility for electoral law and will be expected to give shape to whatever the Prime Minister has now set in motion. He should resist doing so on the terms in which it was announced. A referendum on MMP, if one is to be held at all, should follow proper inquiry, proper consultation and a settled Cabinet position, not a commitment made before any of these existed.
