Fewer Kiwis leaving, more expats coming home and new migrants arriving has increased the amount of slack in the labour market, making wage growth weaker than the Reserve Bank expected.
Only 10 per cent of private sector salaries and wage rates increased in the March quarter, and while it is a seasonally weak quarter for pay rises, that is the smallest proportion for five years; 43 per cent of pay rates have not increased at all over the past year.
However, Mr English said there had been growth in real wages in New Zealand, something that was not common in the developed world.
"We are getting wage growth, relative to inflation it is pretty good, actually. Total wages have been growing 4 to 5 per cent, that is certainly faster than inflation, hourly rates have been growing a bit slower than that.
"The question is what is going to happen over the next two or three years, and the outlook for wage growth is still reasonably positive."
