The minimum wage is set to increase in April next year by $1.20 an hour.
Workplace Relations and Safety Minister Iain Lees-Galloway said the increase to $17.70 an hour would benefit about 209,200 workers and their families.
It would lift wages throughout the economy by $231 million a year, he said.
"About a quarter of those earning the minimum wage - 36,000 people - are parents."
The starting-out and training wages will increase from $13.20 to $14.16 per hour from 1 April 2019, in order to stay at 80 per cent of the adult minimum wage.
The government also announced its planned minimum wage increases for the following two years, as it moves towards a goal of an $20 an hour minimum wage by 2021.
"To provide businesses and workers with greater certainty, I am indicating minimum wage rates of $18.90 to come into effect on 1 April 2020 and $20.00 to come into effect on 1 April 2021. These indicative rates are subject to each year's annual review, in accordance with the statutory process, which will take into account the economic conditions at the time.
"The government carried out wide consultation with employer and worker representatives, including Business New Zealand and the CTU, and listened to the need for certainty on our travel toward $20 per hour minimum wage by 2021," Mr Lees-Galloway said.
New Zealand First's Clayton Mitchell said raising the minimum wage is one part of the government's approach to lift the wellbeing of all New Zealanders, and was a key part of the coalition agreement.
