ANZ's Truckometer is pointing to the economy having pulled out of its soft patch in the September quarter.
The heavy traffic index, strongly linked to contemporaneous economic activity, rose 1.4 per cent last month, on top of a 4.4 per cent increase in October.
"It suggests the trend decline has stopped and supports ANZ's view that the September quarter was a pothole and not a deep ditch," ANZ economist Sharon Zollner said.
The heavy traffic index suggested a negative September quarter gross domestic product out-turn is possible when it is reported next week.
"But the stronger results in October and November suggested a considerably better December quarter may be in prospect."
