A member's bill in an MMP Parliament
Parliament has 120 MPs. The governing Kōwhai Party holds 50 seats, its confidence partner Rimu Party 15, and the opposition 47; the remaining 8 are a crossbench party. A small environmental group, Plastic-Free Harbours, has a 12,000-signature petition and a member's bill drafted by Rimu MP Hana Reid. The bill would require supermarkets to phase out soft-plastic packaging by 2027, with exemptions for small businesses. It passes first reading 61 votes to 59 and is sent to the Environment Committee. The committee receives 1,840 submissions; 1,500 support the bill, but the Kōwhai Party's coalition agreement says new costs for business need a regulatory impact statement. Rimu says it will withdraw support unless the small-business exemption is widened. The group has four months before the committee reports back and a $6,000 budget. It wants to know whether the bill is likely to pass and where its effort will matter most.
1. Map the steps the bill must still pass and identify the points where Plastic-Free Harbours can realistically influence the outcome.

The bill still faces: the select committee report, second reading, committee of the whole House (where amendments are voted), third reading, and Royal assent. The committee stage is where the group's effort is most likely to matter. Select committees are not just talk shops: they can recommend amendments, and MPs often follow their report. The group should make a tight written submission, ask to be heard, and give the committee a draft exemption for small businesses that addresses the coalition's regulatory-cost concern. It should also brief Rimu and Kōwhai MPs, because under MMP the government does not automatically control every member's bill. With $6,000, targeted meetings and expert evidence will go further than a broad advertising campaign. A member's bill also needs to keep winning votes and survive later stages; a first-reading win is only the beginning.
2. The bill passed first reading 61–59. Explain why that vote does not guarantee passage, using MMP, confidence-and-supply, and conscience voting.

First reading is often a vote on principle, not a final text. The 61–59 margin is a bare majority in a 120-seat House, so absences, a changed position, or a committee amendment can flip it. Under MMP, the Kōwhai–Rimu confidence-and-supply agreement binds Rimu on confidence and supply, but not necessarily on every member's bill. Rimu can withdraw support without collapsing the government, and Kōwhai MPs may vote against the bill if the regulatory impact statement shows unacceptable costs. The select committee can widen the small-business exemption, which may attract crossbench votes but lose environmental support. The group should therefore count votes at second reading, not just first, and should not assume that 61 votes is a stable majority. A bill can also be amended out of existence at committee stage.
