Labour has slammed the spending of more than half a million dollars on a programme that uses colours to try and change thinking within the Ministry of Social Development.
"The Government is never slow to call everyone else on wasteful spending - tightening others' belts is a favourite pastime," said Labour's state services spokesman Kris Faafoi.
"Yet here we have a department, whose clients are queuing at food banks, squandering taxpayer cash on a programme that has all the hallmarks of mumbo-jumbo."
The consulting firm Human Synergistics has been hired to implement a programme at the ministry called Building Blue.
The colour blue is used to illustrate desirable behaviour such as achievement and self-actualisation, whereas red and green represent negative behaviours like dependence, Stuff.co.nz reported.
