On 23 August 2023, the Natural and Built Environment Act 2023 expanded the scope of the call-in regime under part 3 of the Overseas Investment Act 2005 aimed at managing national security and public order risks associated with transactions by overseas persons. Businesses involved in an irrigation scheme and having “one or more resource consents under the Natural and Built Environment Act 2023 to take (in total) more than 25 million cubic meters of water per year” are now identified as strategically important businesses under section 3C of the Overseas Investment Regulations 2005. Acquisitions by foreign investors in such businesses may thus be subject to the Overseas Investment Act 2005 call-in regime.
"3C Strategically important businesses
(1) This regulation prescribes classes of businesses that are SIBs for the purposes of the definition of SIB or strategically important business in section 6(1) of the Act. [...]
Irrigation
(6) A business that is involved in an irrigation scheme is a SIB if—
(a) the scheme involves a water supply system for the collection and storage or reticulation (or both) of water primarily for agricultural production; and
(b) the business has 1 or more resource consents under the Resource Management Act 1991 to take (in total) more than 25 million cubic meters of water per year. [...]" (Overseas Investment Regulations 2005 (SR 2005/220), last amended on 24 August 2023, Section 3C)
