The New Zealand government has announced seven changes to speed limits on Canterbury highways, including lowering the limit on a section of SH1 south of Rolleston from 100 km/h to 80 km/h. The adjustments aim to enhance road safety and reduce accident risks in the region. The affected stretch of SH1 is located near Rolleston, a town in the Canterbury region of New Zealand. Officials cited increased traffic volume and safety concerns as key factors in the decision. The changes are part of a broader initiative to review and update speed limits across the country. The new limits will take effect in the coming months, with further details to be released by local authorities.
