The committee said it had told drug-funding agency PHARMAC this alternative device would be more popular than currently-available implants. It would also be more cost-effective over time, the report said.
The Committee said it was harassment of women visiting hospital facilities, and the distribution of offensive material was troubling.
"Women attend medical service providers for a variety of reasons and should be able to enter clinics without feeling they are the subject of coercion or humiliation."
The report also raised concerns about access to services in greater Auckland, especially South Auckland.
The committee said it first raised the issue with Counties Manukau District Health Board in 2008,and had to raise it again this year.
The Committee was made up of Professor Dame Linda Holloway, Reverend Patricia Allan, and Hamilton general practitioner Dr Tangimoana Habib.
