Open Door Policy
The negotiation of the details of the Arrangement (or Open Door Policy as it was then called) was announced on 4 February 1973 by the Australian Minister for Immigration, Mr. A. J. Grassby. Two special emissaries of the Australian government (Mr. G. E. Hitchins and Mr. T. A. Smith of the Department of Immigration) visited New Zealand from 5–9 February 1973 to arrange the details of the implementation of the open door policy agreed upon by Prime Ministers Whitlam and Kirk.
