Major changes are set to make future Official Cash Rate decisions far more transparent. 

The RBNZ's Monetary Policy Committee will release details of who voted which way to the public if they're unable to come to consensus.  

Committee members are also encouraged to speak openly about monetary policy. 

Former Reserve Bank Special Advisor Geof Mortlock told Mike Hosking that he and other economists have been advising Treasury and the Minister to move in this direction for some time. 

He says it’ll strengthen the accountability and transparency of the Committee.
