I think I posted it in the "What has pissed you off today thread", a coincidence that it comes up twice in a short time.

It's either a major fart or a children's toy!

Although I have never heard it for myself, I am told it is quite commonly used amongst golfers who cart their clubs around in a 'trundler'.

I agree with you Vital it does make it sound like a toy and a bit childish but that figures, as Kiwis are quite fond of using toddler language.

Can you imagine anywhere else in the world where you might hear a full grown man say: I'm going to put some bickies and chippies in my trundler.

The White House in Washington DC?

I've gotten used to the different names for stuff here on the South Island but I don't know much about how that varies on the North Island.
I think from tv and stuff that Kiwis universally use the same names for things throughout the country. I don't really think there's much regional difference.
I know I could go from Leeds to Wakefield in the UK and they'd use different names for bread cakes etc but it doesn't seem to be the case here in NZ

The accents are different though, although only very slightly. I can now tell the difference between a South Islander and a North Islander.
