The Waikato Regional Council has been accused by the city council of dabbling in its area of work by investigating inland ports in Waikato.
A $35,000 report commissioned by the regional council on the development of freight hubs and inland ports in the region was to be heard at the regional transport committee this week, but was withdrawn for peer review.
The report, by Aurecon, found there was a need for only one additional high-volume port - such as the proposed inland port at Ruakura in Hamilton - in the Upper North Island in the medium-term.
It also warned further work needed to be done to address issues in staging the Tainui Group Holdings' 30-year development at Ruakura and the effect it would have on neighbouring land uses and surrounding roads.
But Hamilton councillor Dave Macpherson, who was on the regional transport committee until his resignation this week, said the regional council was dabbling in city council business.
