> Even in places known for their extreme weather conditions – such as ‘hot ‘n’ cold’ Otago, wind-prone Wellington and sweaty Auckland – high-performance homes will stay comfortable and fresh all the year round.
All these places stay above 45F and below 80F. This is anything but extreme weather. You don't need any sort of special "high performance" house for this kind of temperate climate.
Living in a true hot n cold New England USA makes me jealous that anyone would consider this extreme. It's sweater n t-shirt weather. I consider hot n cold being 100F in the summer and 0F in the winter.
