Yeah, definitely took a little getting used to for driving over there.
It was what I imagine life here in the states must have been like 50 years ago. Primitive in some respects due to the cultural differences and the fact that they don't import all the b. s. from the states there. There isn't a Walmart or Costco, the grocery stores carry very little that isn't made in NZ and everything seemed to be in smaller quantities and cost about 1/3 more than it does here.
A 12 pack of Coke over there, when I could find one, was about $9 NZ or about $7 U. S.
I'm used to paying $3-4 here. Gas and auto parts were also crazy over there, but having a car over there is somewhat of a luxury compared to here. Many of the places I visited, people didn't own a car,or they only had 1, not the 2 or 3 that U. S. citizens have.
Overall though, I'd highly recommend it. Made me appreciate what we have over here a lot more.
