Hundertwasser presented his Koru flag in parliament, in the media, at various events and via numerous sales channels throughout New Zealand. His flag, which was not intended to replace the official flag of New Zealand, but rather be considered an "indigenous" flag, took many hearts by storm. The issue "A Flag of Our Own" preoccupied the editorial pages of newspapers and magazines, as well as television coverage, it was discussed at schools, and citizens' action groups were formed. Soon, Hundertwasser's Koru flag could be spotted atop the city hall in Auckland, on official buildings in Wellington, on commercial buildings and private residences throughout the country. In 1986 there were more than 1,000 flags. Hundertwasser's Koru flag is popular in New Zealand and is available and used in a number of sizes.
An adaptation of the Koru flag in blue was adopted among the six Flags for Tolerance (Les six Drapeaux de la Tolérance) by Unesco in Paris. The Flags for Tolerance were hoisted on November 16, 1995, on the occasio of the 50th anniversary of the founding of Unesco. They were subsequently made available by Unesco to the 185 member nations.
