Road access is restored to Kaikoura. The Inland Route 70 is now open and State Highway 1 to the south of Kaikoura is open with restrictions.

State Highway 1 is closed to through traffic travelling from Christchurch to Picton

The road is open between Picton and Clarence, and from Cheviot to Oaro.

People travelling between Picton and Christchurch need to use the alternate inland highway route – State Highway 6 and 63 to Murchison, and then along State Highway 65 to Springs Junction and through Lewis Pass (State Highway 7) to State Highway 1 at Waipara.

Up-to-date information from NZTA is available here.

Lower speed limits on alternative Picton to Christchurch route

Consultation is underway on a proposal to convert a range of temporary lower speed limits introduced on the Picton to Christchurch alternate state highway route after the November 2016 earthquake to permanent limits. Information on the proposed changes, detailed maps and a submission form are available here.

NZTA is advising people travelling on the alternative Picton to Christchurch route that speed limits have been lowered in some areas along state highways 7, 65, 6 and 63.

Speed limits had been lowered to improve safety on sections where the road is windy and narrow for more than two kilometres. Speed limits will also be reduced at key intersections, particularly where there is an increase in right turning traffic, including heavy vehicles and campervans.

To improve safety for people living in communities along the alternative route, speed limits through all the townships and villages along the route will be a maximum of 60 km/h. Existing speed limits of 50km/h will not change.

New signage will be installed at all schools along the route to indicate a 40 km/h speed limit when children are present.

There will be also be more signage installed on difficult or unexpected curves.

Freight specific information

  • All 50MAX vehicles and HPMVs that were permitted for SH1 are able to use the alternative route.
  • These vehicles can travel on SH7 to Springs Junction, on SH65 to Murchison and SH6 to Nelson or turn off at Kawatiri onto SH63 to Renwick, onto SH6 and into Rapaura Road (SH62) to join SH1 to Picton at Spring Creek. Freight vehicles are asked to not travel via SH6 through Woodbourne and into Blenheim to join SH1.
  • The Christchurch to Picton journey will take at least 3 hours longer so drivers need to ensure they are well rested before they start, take plenty of breaks and allow for the additional time when planning their schedule.
  • Drivers need to abide by their work-time and logbook requirements when using the alternative route.
  • NZTA are working through the implications of overweight and overdimension vehicles using this route and more information will be available in due course.

Variations to work-time, rest-time rule

“We have had enquiries about variations to the work-time, rest-time rule for the alternative route. This is something we will assess on a case-by-case basis, and in very exceptional circumstances. Our primary concern will always be the safety of drivers and all road users,” NZTA National Manager Operations Kate Styles says.

“We want to make sure that commercial drivers who travel this challenging route are aware of the extra time they will be driving and are rested and refreshed. This road is now a vital lifeline for the South Island and we need to ensure that we do all we can to lower the risks for those using it, such as driver fatigue.”

The alternative route which involves State highways 7, 65, 6 and 63 adds at least 3 hours to a trip between Picton and Christchurch.

All motorists using the road need to be aware this is a narrow, windy route with fewer passing opportunities. The road is getting far more traffic than usual and all drivers need to be prepared for queues and potential delays.

“We have received un-solicited feedback from road users letting us know how courteous truck drivers on the route are being, which is really great to hear,” Mrs Styles says.

Commercial operators and drivers who want to be sent traffic updates for the route via text message are encouraged to email to be added to the distribution list for this service. Once signed up they will remain on the distribution list until the end of summer (Feb 2017).

All High Productivity Motor Vehicles (HPMVs) including 50MAX that were permitted for State highway 1 are able to use the alternative route. However there are some restrictions that are important to note:

  • HPMVs including 50MAX are not to use the short cut of Anglesea Street / Boyce Street, at Renwick to get between SH63 and SH6
  • HPMVs including 50MAX are not to travel via SH6 through Woodbourne and into Blenheim to join SH1
