That is, should institutional investors (particularly, government-owned funds) sell out of any controversial investments or try to bring about positive change from within?
"We believe that our engagement, and that of other investors and of Non Governmental Organisations, has improved the practices at the mine and the disclosure of those practices," Orr said in the statement. "... For us, walking away might be simpler and quicker than staying engaged, it might avoid critical coverage, but it changes nothing."
Although further evidence of these stated improvements is required, it's a good argument - should 'engaged' owners simply sell out to shareholders who don't even have to pretend to care about ESG issues or reveal their interests?
Ironically, NZS leaves itself open to such criticism because it is transparent. It does a good job of explaining how why, and where it invests, including a lengthy 'responsible investment' policy.
But while it tries to do good, according to the NZS statement, responsible investment "is not about making New Zealanders feel good about the (NZS) investments".
