Great video! I will always remember 'tin iggs', which means ten eggs. The 'i' here is pronounced like the first 'e' in the English word 'eagle'. That is typical New Zealand English for me.
There are certain terms in Australian English such as fair dinkum (especially fair dinkum shed) and pangers and mash (not sure about the spelling, it means sausages and mashed potatoes). But I just read a book by a Samoan living in New Zealand (Albert Wendt) and he used as well 'fair dinkum'. I don't remember having heard 'mate' or 'no worries' in New Zealand, so I regard this as Australian English (but I could be wrong).
Don't understand why Clovek's comment below got a downvote...
