Bank notes bearing the signature of new Reserve Bank Governor Graeme Wheeler may not be in circulation till the end of next year.
The Bank says all notes produced since Mr Wheeler took over the governor's position will have his signature on them.
But it will take some time to work through a stock of notes bearing the signature of previous governor, Alan Bollard, who left the bank after 10 years last September.
A spokesperson said how quickly notes bearing the signature of the new governor will be in circulation, will depend on demand for new notes.
Given expected levels of demand it could be late 2014 before the public see notes bearing Mr Wheeler's signature.
