The focus has all been on the highway with the well publicised closures of SH1 south of Kaikoura due to a big new slip between Puketa and Goose Bay. However there has been work on the Main North Line in particular at several overbridge sites at Parnassus, Waima and Oaro where a lot of repairs have been needed. Also the main line and loop are being relaid at Pines just south of Clarence where there is a big problem with an upthrust in the ground of four metres resulting in suddenly changed ground levels, this forced the track well off its normal alignment and has also affected the highway. The nearby Clarence River bridge which is quite a major structure needs significant work and the highway bridge was also affected. At Mangamaunu both the highway and the railway are being realigned around a major slip site, which I think means they are building new embankment and seawall probably. There are also five railway tunnels being repaired.
The aerial photos I have been making use of only cover a coastal strip (I had hoped they would include the inland highway route, unfortunately this is not the case) but Google Earth has updated its coverage for much of the area to cover the timeframe after the quakes, thus we can have a view of the whole route although their resolution is nowhere near as good. However the Linz photos do cover a stretch of SH1 between Hundalee and Oaro which is well separated from the railway line, this is really the only major route differentiation along nearly all of the Picton-Chch highway.
If you want to have a look at the Linz aerial photos yourself in a web browser this is pretty easy to do. Just go to the address below:
On the left side should be the description of the data layer -title is
Kaikoura Earthquake 0.2m Aerial Photos (2016)
You can see near the top left an orange + sign. Just click that (it should then change into a red - sign) and the layer is loaded onto the map shown at the right. Then just drag, zoom, scroll etc that map until the section Parnassus-Ward comes into view and you should be able to see the aerial photos.
