Ah, the Kiwi slang and the epic New Zealand/Australia rivalry, all in the same add!
It’s not that these Kiwis are super tough to understand, but sometimes you have to listen closely and fill in the blanks when you don’t know what they just said. Here’s a little trivia, just for giggles:
“It going to be a cracker of a day” = it’ll be a good day
“Are you winning?” = how’s it going? (particularly on the job)
“those houses are a bit flash” = those are fancy homes
“she’ll be right” = it’ll be alright
we’ll start taking notes and adding more as we remember them.
