maybe an obvious one but
http://www.google.co.nz is one i use a lot..
it's the new zealand version of google and you can check a box that will filter the results so you just get pages from nz.. exactly the same as the co.uk version..
most of the bigger companies you might deal with or want toi deal with will have an nz version of theie site.. ie
http://www.landrover.co.nz
i'm sure there are better examples but its the best i could come up with under pressure..
