The New Zealand government is giving itself more say in overseas investment in this country. A review of investment regulations will see ministers now taking into account economic interests to ensure investment is in the country's best interests. New Zealand Finance Minister Bill English on Monday announced regulations that will allow ministers to take New Zealand's economic interest into account when considering investments in sensitive land. English said a press conference on Monday that ministers will be able to consider a wider range of issues, including large-scale ownership of farmland. The change gives them more tools for rejecting applications, he says. There will also be a new mitigating factor which will require involvement of New Zealanders in investments, such as having a head office here or Kiwi directors on boards. The new regime will take effect in December.
