ASB's Chief Economist Nick Tuffley says business confidence remains low.

"If we do see business confidence remaining low for a considerable period, then we do run that risk that there's a little bit of employment and investment that gets deferred, and that could slow down the economy a bit more in the short term."

He says, in the big picture, New Zealand is fairly stable but that an eye needs to be kept on things like international trade tensions.
