The Finance Minister admits many Kiwis aren't getting as much work as they'd like to be. 

Unemployment has remained unchanged at 5.1% in the March quarter, despite most economists predicting a rise. 

However, 21% of employed people are now working part time. 

Nicola Willis told Mike Hosking the ongoing rise in the under-utilisation rate is a concern. 

She says it's clear that some people are going into part time work rather than full time work, and aren't working as many hours as they'd like to be. 

Willis says she'd like to see those numbers improving.
