He was due to enter pleas to all those charges today, but instead defence counsel April Kelland told Christchurch District Court Judge Quentin Hix that the police had filed a memorandum seeking to withdraw all but one charge.
Kelland said the defence did not oppose the withdrawals.
The defence can sometimes ask for charges to be dismissed so that they cannot be relaid.
Frost is still charged with indecently assaulting a woman overnight on November 28 to 29, and he has pleaded not guilty to that. The charge has been remanded to a case review hearing on February 17.
Judge Hix released Frost on conditions that he live at a specified address in Bexley, have no contact with the complainant and stay a specified distance away from two addresses in Christchurch and rural Canterbury.
