Does New Zealand need a Multiculturalism Act similar to Canada's?

United Future leader Peter Dunne has called for a “multiculturalism act” in light of racist anti-immigration flyers distributed in areas of New Zealand. “UnitedFuture wants to see Parliament pass a Multiculturalism Act, similar to Canada’s, formally recognising New Zealand’s growing multicultural flavour, and further protecting immigrant communities from racism,” Mr Dunne said in the wake of a recent anti-Asian pamphlet campaign in Christchurch.

The flyers, which were dished out in Christchurch and South Auckland, were made by a racially-motivated far right group known as Right Wing Resistance. They are headed by former National Front leader Kyle Chapman.

Mr Dunne said the act would stamp out blatant racism and mark the growing multiculturalism of New Zealand society. “Official statistics already show that almost one in three New Zealanders today are of non-European origin – within the next 15 years that is likely to increase to over 40 percent. “By 2021, for example, a quarter of our population will be of either Asian or Pacific origin. “A Multiculturalism Act should ensure everyone enjoys equal treatment and protection under the law, while formally acknowledging the freedom of all members of New Zealand society to preserve, enhance and share their cultural heritage without fear of persecution,” he said.

The New Zealand Herald reported the leaflets bore the message “Stop The Asian Invasion” and distributors had told people New Zealand was “a country for everyone except Asians”. "He said Asians bring diseases and crime to the country, and New Zealand will be a paradise without them," said the NZ Herald’s source.
