Updating South Island cinemas

I am putting together plans to visit as many South Island cinemas as possible,  beginning in Christchurch and following a circuitous route, in early December.  There are places I haven't been back to for a year or two, and some new places.
As I no longer have any university support to help my endeavours, such opportunities to travel are infrequent and need to make the most efficient use of time--so, I plan to visit more than 20 cinemas in eight days.
