If you think you will have enough collective energy after a 10Hr ??? flight from NZ to HK, I vote you have a look around.
I would take the train to Kowloon - Tsim Sha Tsui & have a walk around the harbour side perhaps take a short ferry ride to the Hong Kong island and have a look around the shops there too. Get some selfies of yourselves on those cute little ferries!

Be aware that Hong Kong has become a theme park for the mainland Chinese so you wont have the time to wait in the Disneyland like queue lines for, say, a tram ride to the Peak. But just to wander around the harbour will probably give you a taste for the place. just enough so you plan to fit in a 2 day stopover on your next visit!

Also be aware of the 'touts', usually Indian, that will target you, so that you visit their uncle's suit shop - they arent beggars or gypsies and mean no harm but can get annoying. The whole place is very safe.

We have eaten at various cafes in the airport and these have been excellent too.
Have fun.
