The only other one not to sign was Martyn Dunne, High Commissioner to Canberra who is not a career diplomat, having worked much of his life in the army before heading up the Customs Department.
Mr McCully said the $9.2 million was from a budget of $398 million.
The letter was sent to Mr Allen on March 15 ahead of an unprecedented meeting of all heads of mission that was to have been held in early April but has been delayed.
It says the New Zealand Ministry of Foreign Affairs had earned an international reputation "as one of the most effective smaller country diplomatic services in the world. We are deeply concerned that the proposals for a new Mfat business model would undermine or even destroy these strengths at a time when we need more than ever to sharpen our international edge."
Mr McCully sought to distance himself from some of the proposed changes last week in an open letter he sent to Mr Allen, and reiterated that he had been given too little time to see the proposals before they went out for consultation.
He said yesterday Mr Allen had not been embarrassed by the letter and had asked him to release the letter publicly.
The original proposed changes would have saved about $25 million a year.
About 600 staff were to have been forced to reapply for their jobs and 300 jobs cut altogether, with more outsourcing for non-diplomatic overseas jobs, cuts in allowances for spouses and children in overseas postings, appointments on merit and not seniority, and diplomats encouraged to specialise rather than be generalists.
