State-owned Landcorp said it had scaled back its plans to turn former forestry land into 39 dairy farms near Wairakei, in the central North Island, saving $25 million to $35 million.
Landcorp said it would "significantly reduce" dairy's footprint from the original plans and instead include alternative uses for the 14,500 hectares of former forestry land it leases from Wairakei Pastoral.
The land-use changes reduce the risk of phosphate and sediment loss and bacterial contamination and should result in a significant drop in the levels of nitrogen leachate, Landcorp said. It is also expected to improve the profitability of Landcorp's development, located 15 kilometres from Taupo.
"Landcorp's strategy is to connect the food we produce on our farms with high value consumers around the world under our new Pāmu brand," Landcorp chief executive Steve Carden said in a statement.
"To do that, we need to exceed their expectations about how that food is produced, whether it is the standard of care for the animals, the people who work on the farm, or the environmental impact of producing that food," he said.
