Before 1974 Niue used the Coat of Arms of New Zealand. The Niue Constitution Act, passed in 1974, provided for a unique seal to be created for Niue. In 1977, after a request from the Niue Assembly, the Parliament of New Zealand passed the Seal of New Zealand Act with an amendment relating to Niue to bring the design of the Public Seal of Niue into line with the other nations in the Realm of New Zealand.
The Seal of Niue has at its centre the coat of arms of New Zealand, which is a shield divided into quarters. In the first quarter is the constellation of the Southern Cross, in the second a golden fleece, a sheaf of wheat in the third, and two crossed hammers in the fourth. Over the four-quarters in the centre appears a white band on which there are three black ships. The shield is supported by a woman dressed in a white robe carrying the flag of New Zealand, representing the population that descended from European immigrants (mainly British), and a Maori warrior armed with a Taiaha, representing the indigenous population. At the head of the shield is a crown, and at the foot of the shield is a ribbon with the words "New Zealand". The Seal is on a white circle, with "Public Seal of Niue" along the top, and "Niue" at the bottom.
It has what looks like a plant arrangement at centre, within a double ornamental circle, itself surrounded by a circle of sea shells. This is crowned with St Edward's Crown (of the United Kingdom). Around above between the two, the inscription PUBLIC SEAL OF NIUE.
Below that, a ribbon carries the motto ATUA NIUE TUKULAGI on two lines, below which two crossed katoua (Niue fighting clubs).
