Improving business confidence is having a positive knock-on effect for commercial vehicle sales in New Zealand, according to the Motor Industry Association.
A total of 10,070 new vehicles were registered around the country last month.
That included 2799 commercial vehicles, which was 36 per cent more than in the same month last year.
David Crawford, chief executive of the Motor Industry Association (MIA), said commercial vehicle sales were "going gangbusters".
The September figures were the highest since records began in 1981.
