Ms Farina said parts of the legislation would require doctors to tell dying patients about euthanasia without specifying what information they would be told.
She believed this created the risk doctors with conscientious objections to euthanasia could leave medicine.
"The other thing that I find particularly insulting is that we do not even know,as we are passing this bill,what information the doctors will be required to pass on to their patients,"she said.
"If it is simply the phone number of the navigator,that might be enough. Will they be required to refer them to another doctor who supports voluntary assisted dying?
"As legislators,we are supposed to be making informed decisions about exactly what this legislation will mean for the people it impacts.
"We stand here today about to pass this clause,which I agree has very little value,without even knowing what we are asking doctors to provide to their patients. I think that is pretty poor legislation."
