On 3 March 2020, the Bill passed its second reading by a narrower margin of 81–39 votes and was referred to a committee of the whole house. On 10 March, a Committee of the Whole House considered and rejected several amendments that included reducing penalties for safe zones, eliminating statutory tests for abortion up to birth, preventing gender-selective abortions, and requiring medical intervention of unintended live births. However, the committee passed two amendments including one by Labour MP Ruth Dyson dealing with conscientious objection and one by ACT Party MP David Seymour eliminating safe zones around abortion clinics.
