It is the first time ministers have rejected a bid to buy a significant landholding in New Zealand since the rules were tightened in 2012, during the Crafar Farms decision, to require the OIO to assess whether a foreign buyer could offer more than a New Zealand buyer would.
Pure 100 Farm is a subsidiary of the China-based Shangahai Pengxin and applied last year to buy the 13,800ha farm, located 32km from Taupo and 92km from Napier, for $88 million.
Ms Bennett said, while ministers recognised the importance of overseas investment, it was a privilege to own "sensitive" New Zealand assets and investors had to meet statutory requirements set out in the Overseas Investment Act.
"After detailed and careful individual consideration, we are not satisfied there will be, or is likely to be, a substantial benefit to New Zealand - a key requirement for applications of sensitive land of this size."
NZ First deputy leader Ron Mark said the ministers' decision to block the sale was "baffling" given the Government had signed off on significant land sales in the past.
