The New Zealand Superannuation Fund has committed $787.5 million into overseas investments over the last year.
The investments include $US100 million in a Chinese infrastructure fund sponsored by BOC International, a wholly owned subsidiary of the Bank of China and Tamasek, a Singapore-based investment company.
The $US426 million fund's aim is to harness the long-term capital appreciation in companies which work in the development, ownership or operation of infrastructure-related investments in China, like water supply and sewage treatment.
The fund also increased its local investment by 6.3% to $3.4 billion over the 2012 financial year.
This includes further purchases of rural assets and increased investment in New Zealand-listed shares including Auckland Airport.
