New Zealand First has introduced a member’s bill to Parliament that would legally define men and women based on biological sex, excluding trans individuals from legal recognition.

According to Reuters, the law, endorsed by party leader and Deputy Prime Minister Winston Peters, reflects the party's position on what it refers to as "biological reality."

Peters condemned the influence of the "deluded left," claiming that the bill will restore legal clarity. However, the law faces long odds because it must be picked from a ballot and passed with a majority vote in Parliament.

Opposition leader Chris Hipkins criticized the idea as "typical populist politics," claiming it diverts attention away from more urgent national issues such as the cost of living and healthcare, Reuters reported.

The bill follows a recent UK Supreme Court decision that only biological women are covered by the Equality Act, sparking controversy about transgender rights.
