Work for a large NZ corporate and we use a security company to manage security and medical risks when travelling and follow their advice - which is good as they don't hype things up that don't need to be hyped up. So we have just cancelled all non-critical business trips to China - so technically you could still go but practically you wouldn't as a visit to China currently means being denied entry from lots of other countries and quarantine etc. Everything else is fine.
Currently in AKL International Lounge waiting to board NZ284 to SIN and initially had the premium heavy config and a light load but was changed to a 787 V1 yesterday so J and PE is full and Y is pretty close to it. NZ283 on the way back in March has a pretty full load as well. Not sure if the light load was the reason for config change or some other reason.
