Hamilton City Council city infrastructure general manager Chris Allen expected any changes required would be minimal and the biggest problem would be increased congestion.
NZTA Waikato/Bay of Plenty state highways manager Kaye Clark said the intersections across the two regions, which span across 2600km of road, had been inspected and did not require works before the change.
Ms Clark said the agency supported any council which wanted to follow Auckland Transport's lead of running campaigns.
Hamilton City Council is planning a more modest $5000 campaign than Auckland Council's $76,000 publicity drive comprising a leaflet drop to 1.73 million households and video updates on the giveway.govt.nz website.
Hamilton plans a 10-day newspaper and radio campaign at a cost of $5000 targeting specific concerns.
The campaign will coincide with the NZTA's $1.2 million national campaign kicking off a week-and-a-half before the new rule is introduced.
