Public-private partnerships have sparked debate, following the release of Health NZ's operating model.

The agency's new operating model mentions private sector participation as an investment option for hospitals- but the Government doesn't believe it's an appropriate way to fund health infrastructure.

NZCTU President Richard Wagstaff says PPPs are a good deal for private businesses- but haven't worked out for taxpayers.

"The Government can always borrow money- if they make a profit, they'd have to borrow money more expensively, and it leaves us really holding the can, particularly if it goes wrong."
