This follows the Ministry of Social Development calling for voluntary redundancies and the Ministry of Health proposing to cut 134 jobs and close the Suicide Prevention Office.
RNZ has spoken to several public servants in different ministries who have been told they might lose their jobs. Many have said the prospect has left them distraught and on edge.
They say the job market in Wellington is already tight, after a crackdown on contractors and consultants last year.
The Public Service Commission revealed on Thursday the number of government workers increased by another 4.1 per cent in the final six months of last year, despite an order to cut costs by the previous and current governments.
Prime Minister Christopher Luxon said the revelation was disappointing, but government departments had since received the message loud and clear about what was expected in terms of staffing numbers.
