The New Zealand Superannuation Fund has a 10.11 per cent stake in Auckland International Airport, according to a notice filed to the NZX yesterday.
The notice was among a number of filings by the fund to reflect the mandating of Milford Asset Management as a manager of some of its investments.
The super fund had a 9.75 per cent holding in its previous filing. Shareholders owning 10 per cent of a company can block any move to compulsorily acquire shares in a takeover of a company.
The fund was set up in 2003 to help pay for the future cost of superannuation.
