What is this mass wasting landform (S 43.571196° E 172.757795°)? I suggest that you view this
landform in Google Earth looking towards the west and zoom into an eye altitude of about 0.1 km (100
meters).
rotational slump
debris flow
translational slide
Correct!
rock fall
Yes. The best description for this mass wasting would be rock fall. This is one
of many events that took place in 2011 associated with an earthquake in
Christchurch, New Zealand. There are a series of blogs on these mass
wasting events:

If you look around this area, you will see cliff collapses where old box cars
have been stacked to catch future boulders that make detach. For example,
look at this area: S43.569629° E 172.757905°
Then, in other areas, people have planted trees to trap future rolling talus: S
43.583376° E 172.718830°
