Cooper also noted how construction was proving a huge employer, with big jobs like the Waterview Connection.
Latest data from Statistics NZ also showed the number of people employed increased by 8,000 from the March quarter to the June quarter.
New Zealand has a working age population of 3.5 million and a labour force of 2.4 million.
"In the June 2013 quarter, the seasonally adjusted number of people employed increased 0.4 per cent (8,000) to 2,242,000. This followed a 1.7 per cent rise in the March 2013 quarter," said Statistics NZ.
Janet Faulding predicted a rise in job numbers.
"As the economy continues to strengthen, we expect to see these positive signs of growth reflected in more and more industries," Faulding said.
"There were 300 opportunities listed under design and architecture on seek.co.nz in September and over 50 per cent were located in Auckland, mirroring the city's property-related construction boom," she said.
Government and defence posted the second largest increase with a 49 per cent growth in roles since September last year while self-employment opportunities increased by 35 per cent and trades and services were up 32 per cent.
New Zealand's biggest integrated construction and manufacturing conglomerate, Fletcher Building, employs 18,600 people internationally in 50 businesses, and has a dedicated employment site - www.fbcareers.com.
Fletcher has 110 jobs advertised globally of which 71 are in New Zealand.
It wants people to fill sales and services, telesales, area manager, driver, machine operator, concrete worker, supervisor and planning roles, as well as many other positions.
"The recruitment team have told me the number of job vacancies listed on our website is consistent with the last four months," said a Fletcher spokesperson.
"They say there's been no particular increase in activity, although seasonally this tends to be a busy time for recruitment as people look to sort things out before the Christmas break."
Low labour costs and a better tax system in New Zealand were prompts for Fletcher to create a new shared services centre in Auckland, responsible for processing and most of the administrative functions of the company's divisions here and in Australia.
