Foreign acquisitions and greenfield investment concerning 'significant business assets' are subject to prior authorisation. Screening applies to the acquisition or control of more than 25% of shares or voting power in a New Zealand enterprise where the total consideration payable or the total assets of the business being acquired exceed NZD 100 million, and the establishment of a new business where the total expenditure to be incurred exceeds NZD 100 million. Additionally, 2020 amendements to the Overseas Investment Act 2005 introduced new powers to manage risks related to national security and other national interests. A ‘national interest’ test now allows the Government to decline consent for certain transactions ordinarily screened if they are considered contrary to New Zealand's national interest. Amendments also established a temporary “emergency notification regime”, subject to review every 90 days, which applies to acquisitions by foreign investors of more than 25% ownership interest in a New Zealand business, as well as certain increases in existing ownership interests, regardless of dollar value. On 22 March 2021, a new “investor test” for overseas investors was introduced, as part of measures adopted in the Overseas Investment (Urgent Measures) Amendment Act 2020. This test seeks to determine whether investors are suitable to own or control any “sensitive New Zealand assets”. This new test focus on the character and capability of investors, made up of 12 factors that include assessing criminal convictions, penalties for tax evasion, corporate fines, and civil penalties. On 7 June 2021, Section 53 of the Overseas Investment (Urgent Measures) Amendment Act 2020 entered into force. This section replaces the emergency notification regime with the permanent call-in regime that should enable the review of investments in “strategically important businesses” to manage investments that may pose a significant risk to New Zealand’s national security or public order. This new regime applies to investments that do not otherwise require consent. Notification of investment is mandatory for some strategically important businesses and voluntary for others. On 5 July 2021, the Overseas Investment Amendment Act 2021, along with its implanting regulations entered into force. Among others, this new reform refine the scope of the national interest assessment by increasing the threshold for transactions caught by an overseas person from over 10% to over 25% ownership. This new amendment also creates new exemptions for lower risk transactions and adds Major Banks to the list of entities considered as “strategically important businesses”. Moreover, this amendment establishes ownership or control interest limits at 50%, 75%, and 100%, refining consent requirements for overseas investments in sensitive land.
