The two McCahons are currently on show on Level 5 at Te Papa, in a short term exhibition alongside Michael Parekowhai and Jim Allen. The exhibitions end on Sunday; I can't recommend enough that you make a visit part of your weekend. And I can't hope enough that we get to see the Robinson out on the floor soon.
