Another's economist's suggesting the Government should be a bit more flexible when it comes to debt and investment.

It committed to reducing the country's debt to 20 percent of GDP by 2021.

BNZ's Head of Research Stephen Toplis says the Government will most likely miss the target anyway, which is low by international standards.

He's joining others in suggesting debt isn't a bad thing if it's spent on good investment and maybe the Government could push out its target.

Toplis told Mike Hosking the precise debt figure is not that much of an issue.

"What matters most is why it is increasing or decreasing. So what we should really be discussing is the quality of the expenditure and the quality of the revenue rather than the number itself."
