Police believe the offending began in November last year and continued regularly until earlier this month when he was arrested.
The intimate visual recordings allegedly started in February.
However, it may not be the end of the charges.
Mr Hislop said there was still an electronic device with which police were having "technical difficulties".
The man was arrested and charged after he was caught allegedly peeping through a window on Sussex St last week.
After an hour-long search, police found the defendant.
Police said detectives carried out a search warrant at a Kingsland address and seized numerous electronic items which were being forensically examined.
The Herald previously reported that on February 25 a Grey Lynn woman saw a forearm holding a cell phone hanging through her open window.
She ran over and hit the man's arm to make him go away.
The cellphone dropped to the floor and was later handed to police, who found images of several people on the phone.
It is unclear whether the case is connected the one before the court.
The 48-year-old was remanded in custody and will be back in court in July.
