This, however, was the highest annual growth in the CPI since September 2011.
Council of Trade Unions economist Bill Rosenberg said low average wage increases of around 2 per cent, although broadly equal to inflation, were hurting workers, especially low-wage earners.
"What we're seeing is people working more hours and also more people getting jobs," Rosenberg said.
"People are feeling fairly pushed because of various pressures in the household budget and deciding both [parents] will have to work to make ends meet.
"At the moment, I'm very concerned we're trapped in a low-wage rut that's very difficult to get out of in the current circumstances.

Workers nationwide worked an extra 0.6 per cent in the last year.
Sean Bevin, from Napier-based Economic Solutions, said growing wages and creating highly paid jobs across the region would require focus on growing already strong sectors.
"We have a very strong primary production sector. In my view, that's where our growth is based and our strengths are based," Bevin said.

The consumer price index recently rose higher than wage growth for the first time in six years. This meant costs of goods and services were likely to rise slightly more than wage growth, at least in the near future.
Westpac senior economist Satish Ranchhod said this would likely put some pressure on wages, and workers would start to feel a pinch.
"Consumer price tends to start rising and then that gets factored into wage growth, and combine that with a firming economy, we should see some wage growth in the next couple of years."
