The company expects its Oregon-based North American business to grow, once new federal regulations on electronic logging devices are announced, Newman said.
The company sees broader opportunity in the North American market coming from new regulation and an international fuel tax agreement which covers 2.9 million vehicles across the US and Canada, and requires accurate reporting of mileage and fuel consumption by state to calculate fuel tax.
The company has developed an indirect sales channel in an attempt to target larger networks serving transport fleets.
"This enables us to address the 4.5 million vehicles subject to one or both of these regulations," Newman said. "This is a substantial opportunity over and above Oregon weight-mile tax services."
Newman will be based in Portland, Oregon, for the next six months to support ERoad's management, training and sales focus in North America. While the North American business hadn't grown as quickly as the company would have liked, its sales were 90 per cent ahead of New Zealand sales at the equivalent point of market entry, he said.
ERoad is now collecting 31 per cent of New Zealand's heavy vehicle road user charges, up from 26 per cent a year earlier and an expansion of its services is aiding its growth, the company said.
Its New Zealand business is expected to continue to achieve strong sales growth in the second half of the year.
The company's staff increased 58 per cent to 180.
The company won't pay a first-half dividend.
