Judge Patrick Grace granted the man interim name suppression until the next hearing on January 28.
The maximum sentence for sexual violation is 20 years and for indecent assault it's seven years.
Last month police investigating claims of sexual assault against some in the Wellington music scene said they have received approximately 20 reports from women.
A spokesperson told the Herald at the time the nature of the reports received relates to sexual offending and assault over an 18-month period.
None of the women were minors. Police said at that stage no charges had been brought and inquiries into the case were ongoing.
Police asked anyone with further information to call 105 and quote Operation Emerald.
