Despite the sentencing being set for yesterday and his defence lawyer John Dean being told to file submissions seven days in advance, he only filed them yesterday morning.
Judge Peter Hobbs said it would be "unfair to insist police continue under these circumstances".
Mr Dean filed an application for a discharge without conviction, as well as an application for permanent name suppression, which Judge Hobbs said police should be given time to consider.
He remanded the matter to February 14 for sentencing.
At the time the offence came to light in 2015, Whanganui health board chief executive Julie Patterson said she "believed no patient has been negatively affected by this doctor".
"While employed by the health board, the doctor was under appropriate supervision. He was stood down immediately, concerns were identified."
