About 5 percent of the population is earning the minimum wage.

About 5 percent of the population is earning the minimum wage - but a lot of us still aren't earning a whole lot more, data shows.

New Zealand's minimum wage is now $23.95 an hour, up from $11 in 2013 and $16 in 2021.

Infometrics chief executive Brad Olsen said government data showed that the percentage of the workforce on the minimum wage had varied between 3.2 percent and 4.2 percent between 2015 and 2019.

It increased to up to about 8 percent after 2019 as the minimum started to step up quickly but when wage growth accelerated after the pandemic, the proportion dropped back to more like 3 percent again.
