Availability of cosmetics in New Zealand?

Yes we have all these products in New Zealand either at the supermarkets or at pharmacies. Depending on where you are, go to a Life Pharmacy for anything you can't find at the supermarket, they generally have everything else. Also try the retail store Farmers - there's one in almost every major town and city. The same goes for Body Shop - you'll find it in the main towns/cities as well. Hope you enjoy your time here :)
