The Trans-Tasman Travel Arrangement (TTTA) is an arrangement between Australia and New Zealand which allows for the free movement of citizens of one of these countries to the other. The arrangement came into effect in 1973, and allows citizens of each country to reside and work in the other country indefinitely, with some restrictions. Other details of the arrangement have varied over time. From 1 July 1981, all people entering Australia (including New Zealand citizens) have been required to carry a passport. Since 1 September 1994, Australia has had a universal visa requirement, and to specifically cater for the continued free movement of New Zealanders to Australia the Special Category Visa was introduced for New Zealanders.
New Zealand's arrangement extends also to Australian permanent residents or resident return visa holders.[1]
