What'd you say?

I've gotten used to the Kiwi Flatmate's accent, and she says that even she usually forgets she has an accent.  But the other day, she was reminded of this during a taxi ride home.  
.
She told the cab driver our address, "East blah blah Street" and the driver had no clue what she said.  "Aces bleh bleh Street"?  She repeated the word "East" several times until he got it.  
.
"You're not from around here, are you?"  he said.  "You must be from somewhere far away, like Tennessee."  
.
"Nope," she said.  "New Zealand."
.
"Oh, is that near the Netherlands?"
.
"Nope.  Australia."
.
"Ah, down in the bottom half."
.
"Yup."
.
Thankfully the cab driver is the first American she's met that hasn't known where New Zealand is.  I know where New Zealand is, but now I'm wondering...where's Old Zealand?  Or is Old Zealand just called Zealand?  
.
Actually, I have an idea where it is.  Maybe it's where you go in your dreams?  Get it?  Z-land?
