Green Party staff have written to their MPs complaining about being undervalued, and suffering from low morale and poor treatment that has damaged the party's reputation.
Staff have sent a letter to MPs criticising the party's management of the transition into Government over issues such as staffing.
It is the first time the Green Party has had ministerial roles, but at the same time the caucus has been slashed from 14 MPs in 2014 to eight MPs.
"MPs and senior staff should now be fully aware of the damage to staff morale created by this drift away from Green kaupapa," said the letter, obtained by RNZ.
Staff had been left with the "distinct impression they were not valued" or that they had "defects" in their work.
