One new addition to the Social Report this year is a section on representation of ethnic groups in government. The graph speaks for itself about what MMP has meant for ethnic representation:
Members of Parliament identifying as Māori, Pacific peoples or Asian 1984–2008, and Māori, Pacific peoples or Asian share of the total population
The bars are percentages of MPs, the dots (taken from census data) are percentages of the population. So, we have a way to go yet, but MMP has still resulted in a massive improvement and given us a Parliament that looks a lot more like New Zealand. That will likely disappear if the electoral system is changed - a tremendous loss to the legitimacy of our political system, and to New Zealand.
