Prime Minister John Key says he is guilty of not being precise enough in his comments about the drinking age, but is shrugging off criticism.
Mr Key told reporters he voted for the drinking age to be raised to 20, when in fact he voted for it to stay at 18.
The Labour Party says Mr Key either had a brain fade, or was not telling the truth.
Green Party co-leader Russel Norman says the memory lapse is concerning given Mr Key runs the country.
The Prime Minister admits he was not as precise as he could have been, but believes the opposition MPs are being a bit pedantic.
