issue of stamps inscribed “Ross Dependency” in 1994, “due to local and international demand.” A definitive set was issued in 1994, and pictorial sets of five or six stamps have been issued annually since then. The denominations match those of contemporary New Zealand stamps. However, the stamps are not generally valid on New Zealand mail. Mail from the Ross Dependency is processed by the “Ross Dependency Agency”, located at a post office in Christchurch. Members of the public (mostly philatelists and stamp dealers) are able to post items bearing Ross Dependency stamps at this office. Mail is canceled with the inscription “Ross Dependency Agency, Christchurch.” See also Postage stamps and postal history of New Zealand References Further reading Duns, Robert J.
