Companies would therefore be excluded from the NZ Super Fund if they were involved in the manufacturing and cultivation of cannabis for recreational use.
They would also be excluded if their main business was to supply recreational cannabis to the public or to other companies (for example wholesalers, retailers or dispensaries); or provide support services for the recreational use of cannabis, the fund said.
The move is a precautionary one, as the NZ Super Fund does not currently hold any of the companies identified for exclusion.
The NZ Super Fund, recently named one of the world's leading responsible investors by Bretton Woods II, received an A+ for responsible investment strategy and governance in a UNPRI benchmarking assessment earlier this year.
Currently, the majority of publicly listed companies involved in the recreational cannabis industry were small in size, but further growth and the inclusion of the companies in market indices was anticipated.
"We will continue to monitor the sector."
Exclusions were just one part of the fund's responsible investment strategy, which focused on the integration of environmental, social and governance risks into investment practices and the implementation of engagement and active ownership practices.
The NZ Super Fund also excludes companies involved in:
• manufacture of cluster munitions
• manufacture or testing of nuclear explosive devices (NEDs)
• manufacture of anti-personnel mines
• manufacture of tobacco
• processing of whale meat.
