[[Statistics New Zealand]] defines urban areas in New Zealand, which are independent of any administrative subdivisions and have no legal basis. There are four classes of urban area: major urban areas (population 100,000+), large urban areas (population 30,000–99,999), medium urban areas (population 10,000–29,999) and small urban areas (population 1,000–9,999). As of 2021, there are 7 major urban areas, 13 large urban areas, 22 medium urban areas and 136 small urban areas. Urban areas are reclassified after each [[New Zealand census]], so population changes between censuses does not change an urban area's classification.
