Double taxation agreements are tax treaties between two countries. These agreements come into effect when a person is a tax-resident of both New Zealand and another country.

Double Taxation agreements prevent the situation of taxation on one income by two countries, through coming to an agreement as to what incomes will be taxed in the country of residence and exempt in the country of occurrence. It also deals with the opposite case where the income will be taxed at the country of occurrence and compensation arises in the country of residence.
Double Taxation also extends to more comprehensive sharing of tax information between tax authorities.
