Holiday Shopping in New Zealand - Goods and Services Tax

No.  Goods or services purchased while you are here in New Zealand are liable for all local taxes,  as mandated by New Zealand law.

However, there are a select few store who have a duty free agreement to sell items without GST applied. Items purchased at these stores are likely to be sent to the airport for collection, or shipped directly to your home overseas. Usually this is only possible on high value items.
