The country's 32 regional tourism organisations sent in 370 nominations - which with the help of bodies including the Tourism Industry Association were whittled down to a list of 101 essential experiences nationwide.
Entrants included Cape Reinga for its surfing and Maori heritage; Waitomo for its glow worms, caves and rafting; and digging a natural spa at Coromandel's Hot Water Beach.
A few commercial entities, including Auckland's Sky Tower, were on the list by virtue of their iconic status.
People will be able to access the list online, searching by region or by categories, including sport, history and scenic splendour.
Hard copies will also be available from sites such as tourist information offices and certain service stations.
The website will have a page for each item and place for people to post blogs and rate their experience on a scale from 1-10.
