Seven upper North Island council's have come together and released a report on the state of the combined region.
The Upper North Island Story was released today by the Upper North Island Strategic Alliance (UNISA), which formed in 2011 by seven district, city and regional councils across Waikato, Bay of Plenty, Auckland and Northland regions.
UNISA said in a statement the report identified the need for collaborative investment and planning to tackle increasing pressure on housing, infrastructure, natural resources, skilled labour and transport systems.
Auckland Mayor Phil Goff said it was a step towards aligning local and central government priorities to support economic growth, good living standards and healthy environments.
"From Northland to Waikato, the Upper North Island supports 53 percent of the national population and generates 52 per cent of the country's Gross Domestic Product (GDP).
