New Zealand will need about another 1000 wind turbines to fulfil a government projection of 3390 megawatts of extra wind energy by 2050, Wind Energy Association chief executive Grenville Gaskell says.
The biggest hurdle would be the Resource Management Act, but while there would be challenges around "consenting issues" there were no economic or technical obstacles, he said.
"If the demand is there, the wind energy can be built."
