NZ99 Auckland-Tokyo had to return after a whole lotta shaking, followed by engine shutdown...

Yep NZE by the look of it

That RR Trent 1000 again... a year ago, ANA grounded its 787 fleet due to turbine corrosion/cracking.
At the time the NZ CAA released a statement that it
"was closely monitoring the action Air New Zealand is taking with Rolls Royce and is satisfied the necessary steps are being taken to ensure the ongoing safety of the travelling public."
The big twins gained acceptance for ETOPS because engine reliability had improved.
Mmm I never want to be aboard a big airliner with half the power out, somewhere over the Pacific.
What was that thing Virgin said, before they dumped the A340's?
4 Engines 4 Longhaul

So the A380 is my choice of ride for anything beyond a jump over the Tasman.

Yes it could have been interesting halfway to Argentina.
All I have heard via the grapevine is that the intermediate stage compressor disintegrated.

It's a systemic problem, and now affecting worldwide Christmas traffic

Airbus must be glad the Trent XWB hangs off their A350, it is a much-developed version of the Boeing -1000 engine.
The 787-9 should have been the model that cleared the earlier issues of that programme, seems not.

I think the latest versions of the 1000 the 1000 TEN has changes that were part of the XWB engine and making it 'less' susceptible to this issue, and crew room gossip is that all the ones being sent to Singapore to be fixed are coming back in the new configuration.

I am wondering how the engines are sent?
You can't FLY them there... presumably an airframe stays grounded until it has at least one guaranteed engine??

I seem to remember the early 707s had a fitting to carry an engine under the fuselage, for just this kind of thing. These days they probably just shove them in a 747F.
