This page is less about a single clinic and more about how the larger radiology brands are positioned across New Zealand. Some look broad and multi-city. Others look strong in one metro area or one region without trying to cover the whole country.
That difference matters because network shape changes what a provider means in practice. A large spread can mean more branch choice within the same brand. A tighter local footprint can mean a provider is especially important inside one market even if it is not visible everywhere.
