Chief District Court Judge Jan-Marie Doogue has made a strong plea privately to Attorney-General Chris Finlayson to address the falling number of judges, a confidential letter shows.
The letter from her to Mr Finlayson was leaked to Labour justice spokesman Charles Chauvel - another embarrassing leak for the Government after a series of leaks from the Ministry of FOreign Affairs and Trade.
The letter dated May 2 was copied to all 147 district court judges and Mr Chauvel said he was sent four copies of it - none from Judge Doogue.
It expresses concern at Ministry of Justice advice that 23 district court judges would be surplus to requirement in upcoming years because of the impact of policing excellence and a drop in crime.
She pleads a case for Mr Finlayson to at least extend Acting Warrants for retired judges willing to continue "in the face of an inability to secure new judges to replace those who have retired."
