Judith Collins says she believes public service productivity has increased under her Government.  

It's on track towards the goal of cutting $400 million off contractor and consultant spending - with a forecast it'll cut more than double that figure.

The Public Service Minister says it's not a case of just shifting work onto public servants, because the service as whole shrank four percent in the year to June. 

"Quite clearly, people are working better - but more people are focused, I think, on delivering better results for taxpayers."
