The internal economy is based primarily on barter, with residents producing much of their own food and sharing supplies from passing freighters or large fish catches communally. When money is used, the New Zealand dollar is the standard currency, but easily-exchanged currencies such as US or Australian dollars or UK pounds will be accepted.

The main locally-produced items for sale are handicrafts especially woven baskets, models of the Bounty, and carvings of local wildlife out of miro wood harvested from Henderson Island and honey, and the island's postage stamps also available by mail overseas are of interest to philatelists. Anything else has to be imported, and is priced accordingly.
