Without action, Auckland faces a shortage of business-zoned land, potentially hampering manufacturing, transport, storage, construction and wholesale trades.
An Auckland Council document studying the effect of the Unitary Plan on business has examined the city's growth potential and says more land is needed if the city's productivity and employment expansion are to continue.
South Auckland, the northwest and the Warkworth/Silverdale areas are tagged as having the potential for growth because there is land for expansion there.
The document, Shaping a Business-friendly City, released today, said economic growth was one of the main drivers of the 30-year Unitary Plan.
"The challenge, as set out in the Auckland Plan, is to accommodate over the next 30 years up to 275,000 new jobs, up to one million more people, at least 1400ha of additional business land and an average expected demand for 13,000 new dwellings per year," it said.
