Consumer spending had gained momentum, Auckland was enjoying strong visitor numbers and dairy prices, and had proved resilient in the face of a high New Zealand dollar and weakening Australian economy, he said.
"Businesses have been taking on additional labour to cater for projected demand, but the outlook for employment growth is very much dependent on the strength of domestic activity, particularly housing activity and consumer spending," Cooper said.
But wages are not shooting up.
"Wage pressures remain contained, average weekly earnings growth for full-time-equivalent employees moderated from 3.7 to 3.3 per cent, largely reflecting compositional effects - annual growth in the labour cost index, which takes into account changes in industry and occupation shares, was unchanged at 1.7 per cent," he said.
Job growth should continue this year.
"The outlook is for solid employment growth and a further decline in the unemployment rate through 2014 back towards 5 per cent.
"However, there are plenty of upside and downside risks to this outlook, both domestic and external," he said.
Cooper's Auckland Economic Quarterly found Reserve Bank LVR limits had constrained housing demand. "Their effect will be compounded by rising interest rates through 2014. However, demand is currently being bolstered by exceptionally high levels of net migration, which together with rising household incomes will help cushion house price growth," he said.
Shamubeel Eaqub, NZIER principal economist, said Auckland was extremely divided on income, and success was not evenly shared.
"While the median household income is $107,900 in the Upper Harbour local board area, it is less than half in Mangere-Otahuhu at $59,900," Eaqub said, adding there are fewer blue-collar jobs.
"This has been hard on places like Mangere, Otahuhu, Otara, Papatoetoe and Manurewa where there has been little or no growth in jobs over the last seven years, even though Auckland as a region is doing much better."
