Please consider the high costs of building material.
High cost for building materials and labour is acceptable due to NZ's remoteness to the rest of the world. I highly doubt this will change because NZ doesn't have the population to warrant any real benefit from economies of scale.
New houses built in NZ are mediocre compared to Europe.
While this is true if you compare on a like for like basis, it is clear that NZ's climate is very different to the climate in Europe. I've mentioned in other threads that new houses built in NZ are a considerable improvement over older houses built 30 or 50 years ago. It's not an issue about 'good bones' - in fact many of the older building techniques in old houses are not approved under current earthquake standards.
I've been over the subject of modern builders (which are more of 'assemblers') vs old builder that would build a house out of lifts of timber - piece by piece. Neither method gives a better house. In fact last week I was at a open home nearby and the realator (Brian Buckingham of Holmwood Harcourts) had no idea what he was speaking about "high spec" and informed me the owner built the house piece by piece (no pre-fab pre-nailed timber framing was used). While his exact words were "It's the only way to build a house" - I was quick at pointing out what a higher standard should look like. I asked if there were construction photos to prove his statement was true? I explained around the kitchen island that high spec would have no joins across the front panel of the island (instead of using 2 or 3 pieces butted up to make a continuous long piece). High spec doesn't mean having a granite top or stainless steel appliances.
If there's any issue of buying a house - be sure to closely inspect houses built around 1998 - 2004 as houses during that time were allowed to be built without using treated timber. Futhermore there were a lack of detail to flashings and the rise of new cladding methods such as the EIFS cavityless direct fix cladding where only the coat of paint was responsible for keeping the water and moisture out. While all the new houses being built today may look boring, 1 thing certain is they will not fall in the mistakes of leaky house syndrome.
