the retention of MMP are: The system allows everyone's vote to be counted equally. The number of votes received by a party is proportional to the number of seats it obtains. The system allows parliament to reflect more representative cross-section of the general population. The system has allowed more women, Māori, Pacific Islanders, Asians and minorities to become MPs. The system produces stable governments, and changing voting systems would produce political instability until the system beds in. MMP is flexible and the system can be altered to suit. Voting for MMP will trigger an independent review to improve the system. Changing system without first fixing the current system is "throwing the baby out with the bathwater" In favour of changing system The Vote for Change group has been established to mobilise support for a change in the electoral system. It is headed as spokesperson by Wellington lawyer Jordan Williams, and the group is supported by multiple people, including former Crown Minister Michael Bassett, former chairman of Telecom (and main opponent of MMP in the 1993 referendum) Peter Shirtcliffe, and former Mayor of Wellington Kerry Prendergast. Bob Harvey, former Mayor of Waitakere City, withdrew his support for the group on 3 July 2011 over allegations another founding member had white supremacist links. Major arguments for a change of system are: MMP has led to parties holding power over MPs, and voters can't easily hold government and MPs accountable The current configuration allows MPs voted out by their electorate to re-enter parliament via the party list (the "backdoor") Smaller parties currently hold a disproportionate amount of power in forming governments. There should be more certainty to voters in government formation more of the time, rather than having to wait for post-election negotiations. Governments should be held to their promises, rather than having to compromise on promises in coalition and confidence-and-supply agreement. There are too many list MPs serving the party executive rather than being accountable to the voting public. There needs to be a proper debate – the 2011 referendum will be lost in the excitement of the 2011 Rugby World Cup (which New Zealand hosted between 9 September and 23 October), so voting to change will allow a proper debate to take place at the second referendum. Voting for MMP will allow MPs to manipulate any changes to the system to their own benefit. Peter Shirtcliffe, who campaigned against MMP in
