(c) (i) In the exercise of command over armed forces which the New Zealand Government has assigned, or may assign, for the local defence of New Zealand, the New Zealand Chiefs of Staff will be the Agency through which such local command is exercised.
(ii) In the exercise of command the principles of command as set forth in paragraph 14 of ABC-1 are applicable.
(iii) With regard to the possible movement of New Zealand forces out of New Zealand territory, the following by the United States Chiefs of Staff to the President is self-explanatory:
‘Proposals of the United States Chiefs of Staff (for operation in the Pacific Ocean Areas) made to the President as United States Commander-in-Chief are subject to review by him from the standpoint of higher political considerations and to reference by him to the Pacific War Council in Washington when necessary. The interests of the Nations whose forces or whose land possessions may be involved in these military operations are further safeguarded by the power each Nation retains to refuse the use of its forces for any project which it considers inadvisable.’
