Ministers have gone against an Overseas Investment Office recommendation, declining a bid by Chinese-owned Pure 100 Farm Ltd to buy Lochinver Station.
The Overseas Investment Office had recommended it be accepted in what Associate Finance Minister Paula Bennett described as a "finely balanced" decision.
However, ministers did not believe the benefits to New Zealand were great enough and used their discretion to reject it.
"While the OIO said the question of whether the benefits or the potential investment to New Zealand are, or could be, substantial and identifiable was finely balanced, it recommended approving the application.
"We agreed parts of the proposed investment could benefit New Zealand but our judgment on the overall balance of evidence the benefits are not likely to be substantial and identifiable."
