This Act may be cited as the Immigration Restriction Amendment Act, 1931, and shall be read together with and deemed part of the Immigration Restriction Act, 1908 (hereinafter referred to as the principal Act).

In addition to the restrictions imposed by the principal Act upon immigration into New Zealand, the Governor-General, on account of any economic or financial conditions affecting trade and industry in New Zealand or any other conditions whatever which render it expedient so to do in the public interest, may from time to time, by Order in Council, make regulations prohibiting the landing in New Zealand of persons of any specified nationality or race or of any specified class or occupation, or limiting the number of any such persons that may land in New Zealand during any specified period or periods.

Any such regulations may apply generally to all persons of the specified nationality, race, class, or occupation arriving in New Zealand, or to such persons when arriving from any particular country, port, or place, and may be made to continue in force for a specified period or until revoked.

No person to whom this section applies shall land in New Zealand unless he is in possession of a permit to land therein granted by the Minister or by some person appointed by the Minister to grant such permits. A permit under this section may be granted subject to such conditions (if any) as may be prescribed or as may, in any case, be imposed by the Minister.

The Governor-General may from time to time, by Order in Council, declare that this section shall apply to all persons or any particular persons or classes of persons arriving in New Zealand, or to all persons or any particular persons or classes of persons arriving in New Zealand from any particular country, port, or place, being in any such case persons to whom, whether by reason of British birth and parentage or otherwise, Part I of the Immigration Restriction Amendment Act, 1920, does not apply.

Every such Order in Council shall have effect according to its tenor, and may at any time in like manner be amended or revoked.

If any person lands in New Zealand in breach of this Act or any regulations thereunder, he shall be liable on summary conviction to a fine of one hundred pounds and shall be deemed to be a prohibited immigrant for all the purposes of Part II of the principal Act; and all the provisions of that Part shall accordingly apply in respect of such person, and in respect of the ship in which he travels and the master and owner thereof, and in respect of the persons referred to in section twenty-five of the principal Act.

This Act shall continue in force until the thirty-first day of December, nineteen hundred and thirty-three, and no longer.
