A police summary of facts stated most of the offences happened after Geddes approached two women separately, a few hours apart, in Napier nightspots in early September, and obtained their phone numbers.
Both later started to get multiple "No Caller ID" calls, few of which they answered, but when they did Geddes was warned to stop.
He told one woman that if she called police he would give her number to his friends. Dozens of further calls were made, including 108 calls to one of the numbers in just three weeks.
Geddes is no stranger to phone stalking.
In 2018, police found Geddes in possession of a 24-page dossier with 2000-plus names. After tracing his outgoing calls, police had discovered Geddes had made multiple "hang-up" calls, with over 300 on one night.
Before Tuesday's sentencing, Geddes had 12 previous convictions for misuse of a telephone, with five involving multiple offences.
