Meridian Energy is planning an 80.5MW wind farm in the Greta Valley, north of Christchurch. Its an area of the country which doesn't have much generation in it, and which therefore relies on power imported from elsewhere. A local windfarm will relieve that problem somewhat, as well as shifting the balance further towards renewables and away from dirty fossil generation.
Neighbours are already objecting on the basis of the turbines "spoiling their view", but the Environment Court has repeatedly ruled that that is not a good reason to reject a project unless the landscape in question is recognised as having outstanding local or national significance. While I don't doubt the locals love their view, there's nothing particularly special about Greta Valley. If they want their objections to be taken seriously, they'll need to find some better reasons for them.
