I understand that the select committee sought advice on this "benefit to New Zealand" test. There were some concerns expressed that this test would preserve incentives for foreign investors to convert farmland to forestry, and after receiving advice on it, the select committee "heard that the benefit to New Zealand test will reduce the risk of losing highly productive farm land to forestry because it requires investors to demonstrate benefits that are proportional to the land's sensitivity. For example, highly productive farm land would require a correspondingly high benefit."
