The "super city" of Auckland is now home to a third of New Zealand's population and economy and it is growing quickly. Official estimates predict most of the country's population growth will happen there, putting the city on track to account for 40 percent within 20 years.
The Reserve Bank has announced measures to deal with the city's house price boom, which the bank says is skewing the national economy.
But the city's astronomical rise is alarming the provinces, who say their contribution to the national economy is being ignored.
In this Insight, Ian Telfer, digs deeper into Auckland's dominance, and investigates whether it is in the national interest for Auckland to be the focus for investment, jobs and immigrants.
Is Auckland a shining star leading New Zealand towards a better future or is it a black hole sucking in resources and limiting this country's attempts to keep up with the rest of the developed world?
