Booked an NZ trip for my brother's family of 4. CX421 (TPE 1210 HKG 1420) connecting to CX199 (HKG 1520 AKL 0735), there are only 60 min in between. I transfer thru HKG all the time, and like
QRC3288 said, even less than 60min is more than sufficient, and I am on rev J ticket. For this NZ trip, however, the TPE-HKG leg is on BA miles, and HKG-AKL leg is on AS miles. And it seems CX only has two daily flights out from HKG for this route. For a family of 4 with kids and not a frequent visitor thru HKG, I am afraid they might not be able to make it if there is any delay for CX421.
For the first question, I remember several times I've heard the captain saying we're still waiting for the connecting passengers, but then, it must be a big group

According to EF, the average delay of CX421 is 41 minutes, a very big risk. This is a flight coming from ICN into TPE.
There are three other CX hlights departing between 10 and 11:15, I would strongly advise to book those.
I know that it is not easy to change an avios booking for four pax, but ...
