Pantry to me: a small walk in cool-room from the pre-fridge era. Essential features being a cold stone slab, ventilation window with no glass but fly screen, a "meat safe" which was a cupboard with a flyscreen door and storage in general. In the UK I lived in a house with this feature built in the house dated from the 1950s. Here in Rural Spain I have seen similar rooms-come-cupboards in all old houses. In Spanish a pantry is "alacena".
I'm another NZer who always thought that the definition of a pantry was just a large cupboard for keeping food in, whether walk-in or not. My grandmother's house had a safe from the pre-fridge era, and at the ski club hut my family used to go to in the central North Island the safe is still in use instead of a freezer, since it's below zero (Celsius) outside in winter.
it is called pantry in an aircraft as well as on a boat. why? because it is more a place to heat up+ some food than to +prepare (cook) it. 'cupboard' maybe because the place is mainly used for the 'storage' of the food. in german some upscale real-estators always call everything a 'pantry-kitchen' (ger.: 'pantry kueche') because they know that the only device the new owner will make use of is the microwave oven - and the refrigerator. a 'kitchen' sounds like a dirty place, a 'pantry-kitchen' sounds like a party place...

I knew what crockery was, it was the "delph" I was wondering about. Does it comes from Delft in the Netherlands?
