Issue stamps for uninhabited regions - valid only in a certain bureau in Christchurch.
Ross Dependency stamps have the sole purpose to be sold to collectors. They never see the territory whose name is written on them: they may be used only in the 'New Zealand Post Ross Dependency Agency' in Christchurch. In Christchurch, however, are enough post offices with ordinary New Zealand stamps ready to be used: That makes the Ross Dependency stamps completely unneccessary.
