Labour has released another confidential cable, this time from New Zealand ambassador to Japan Ian Kennedy, highly critical of the proposed restructuring of the Ministry of Foreign Affairs and Trade (MFAT).
It is the latest of an embarrassing series of leaks to Labour, which have included criticisms from the High Commissioner to Singapore and the Ambassador to Argentina.
Labour's Phil Goff also claimed on Thursday that MFAT chief executive John Allen had instructed ambassadors this week not to put their criticisms in cables.
The restructuring would lead to job losses of up to 300 positions, many of them administrative staff seconded to overseas postings, a reduction in some overseas allowances, and the end of a diplomatic appointment system based on seniority over merit.
Labour leader David Shearer says the fact that the cables are still being leaked, despite an edict trying to stop them being sent "indicates just how deep the concerns are among our most experienced diplomats."
