Transmission Gully Speed Limit Raised to 110 km/h from February 2026
Transmission Gully will have its speed limit raised to 110 km/h starting 16 February 2026, following strong public support and safety assessments confirming the road’s suitability. This change applies to the 27-kilometre section between Linden and Paekākāriki, while heavy vehicles and trailers remain limited to 90 km/h, and the Raumati Straights section will retain a lower limit due to safety and design constraints. The government emphasizes ongoing safety enforcement, monitoring, and potential future upgrades for sections not meeting the higher speed standard.
