What is the English Language Bill and what would it actually do in New Zealand?

New Zealand's Parliament is set to decide on the English Language Bill, which aims to make English an official language. The bill is currently before a select committee and is likely to come to a final vote before November's election. The bill is short, with only five lines, and states that its purpose is to provide legislative recognition of English as an official language. According to University of Otago law professor Andrew Geddis, the bill will have 'literally no practical consequences at all' and will not affect the current legal rules, practices, or procedures. The bill does not lay out any instructions, punishments, or restrictions on other languages and would not impact the use of Māori or English Sign Language. The introduction of the bill was part of the coalition agreement between National, ACT, and New Zealand First parties.
