MMP campaigners have hit out at Don Brash's call for New Zealand to ditch MMP for the supplementary member (SM) system.
According to this morning's New Zealand Herald, Dr Brash says he does not support returning to first past the post, instead pushing for SM.
Under SM, only a fraction of the total number of seats is allocated by a proportional vote.
“SM is an unpopular and discredited electoral system that sustains the worst aspects of first past the post,” says Sandra Grey, Campaign for MMP spokesperson.
“Under SM the votes of hundreds of thousands of New Zealanders will be wasted as people’s choice of party would only be allocated to 30 list seats.
“Just like first past the post, this is likely to mean New Zealand will be governed by a political party that does not have the support of a majority of voters.”
Under MMP in its current form, the party vote directly relates to the number of seats a party receives in Parliament, provided it wins an electorate seat or 5 percent of the vote.
Under first past the post, whichever party wins the most electorates wins – the actual share of votes doesn't matter. The most notorious example of this in New Zealand election history occurred in 1981, when Social Credit got 21 percent of the vote, but only two seats in Parliament.
"That doesn't feel quite right in my view, so you do want a way in which small parties can have some representation in Parliament," says Dr Brash.
But his preferred system – SM – isn't proportional either, and nor is it popular with the public.
“Only 5.6 percent of New Zealanders supported SM the last time it was tested, at the 1992 referendum," says Ms Grey.
"More recently only 4 percent supported SM in last year’s UMR poll, down from 9 percent in their 2009 poll.”
SM is considered a combination of FPP and MMP, but does not deliver proportional results, favouring parties with larger shares of the vote. Compared to MMP, it is easier for parties to form a Government without coalition partners.
Prime Minister John Key is also believed to support SM.
