Ms Collins' silence on the issue contrasts with what Mr Collin described as detailed consultation with the Law Society on the implementation of the reform bill.
He said family lawyers were divided over the current violence provisions and the Law Society's written submission supported repealing them, arguing that another clause requiring judges to protect child safety allowed "a wider inquiry".
However, Mr Collin's predecessor as chairman of the family law section, Auckland lawyer Antony Mahon, said he believed the criteria for judges to follow when violence was alleged should be written back into the bill.
Both lawyers and Ms Hannifin also urged the Government to drop a proposed $897 fee for private mediation, which would be compulsory for anyone seeking access to the court on a custody or contact issue except in violence cases.
Mr Collin said there was no sign that the fee was being rethought.
