The NZTA have released a handy info guide in regards to travelling to Kaikoura this summer. 

Are you aware of the opening hours and night closure areas of the SH1 north and south of Kaikoura?

From 15 December, there will be more options for travel around the upper South Island. The alternate route (via state highways 63, 6, 65, 7, through Lewis Pass) is open 24/7. Both SHI north and south of Kaikoura will be open during daytime hours 7am – 8:30pm and closed at night for safety. Don’t forget Kaikoura is still accessible 24/7 from the south via the Inland Road (Route 70) just north of Culverden.

Plan your journey between Picton and Christchurch according to the route which is best for you, based on where you are going and the time you are travelling. www.nzta.govt.nz/p2c
