"People seem a bit more secure and think 'summer is here so it's time to build'. There is more confidence out there, more job security," he said.
Northland trends reflected a similar increase nationally for new dwelling consent permits.
Nationwide, the seasonally adjusted number of new dwellings consented during the month of October 2014 increased by 8.8 per cent over the previous month - after decreasing 12 per cent in September.
Statistics New Zealand business indicators manager, Neil Kelly, said long term building consent trends were expected to continue improving in the following months.
"In the seasonally adjusted numbers, we have actually had a bounce back in October but it's a bounce back after a fall the previous month."
The regions which consented the most new dwellings in October were:
-Canterbury - 686 (including 34 apartments)
-Auckland - 591 (including 106 apartments)
-Waikato - 194 (including 12 apartments).
More than $1.3 billion of building work was consented.
