In Auckland, where increased migration has led to a shortage of housing, dwelling consents rose 20 percent to 643 from the year earlier month. The Waikato region recorded the largest increase, with consents jumping 98 percent to 320 from September last year.
Auckland consent numbers are running at an annual level of about 8,700 which is "way below what is needed to meet the long-term shortage in housing that Auckland is experiencing," Westpac's Norman said.
Meanwhile, Wellington recorded the biggest decline in dwelling consents, with a 35 percent drop to 126 from the year earlier month. Consents in Canterbury declined 9.3 percent to 525, as the residential phase of rebuilding earthquake-damaged region winds down as non-residential activity picks up steam.
"We expect that trend to continue as commercial and anchor projects get underway," Norman said.
The value of non-residential work rose 28 percent to $619 million in September from the same month a year earlier, while the value of residential work rose 17 percent to $911 million.
The value of all construction consents rose 21 percent to $1.53 billion in September from the year earlier month. On an annual basis, the value of consents 12 percent to $16 billion.
