The move by KiwiSaver funds to exit investments in tobacco and controversial weapons has seen a massive spike in the amount of money invested responsibly in New Zealand.
Investment by funds which screen out the nasties has grown from $1.6 billion to $42.7 billion in the last year, according to the latest Responsible Investment Benchmark report.
Simon O'Connor, chief executive of the Responsible Investment Association Australasia, said the jump was primarily due to the negative screening of multiple issues by the majority of New Zealand's KiwiSaver providers.
"This is a staggering increase and is a monumental development for New Zealand's financial markets."
"We have never seen a market switch so rapidly to responsible investment. It's one of the most significant global changes to happen to the sector in 2016 and highlights that New Zealanders are not prepared to build their retirement savings at any cost," O'Connor said.
