By Labour's own logic, this law is attempting to fix a problem that does not exist. Labour's support for this legislation actually shows a lack of confidence in themselves. They must believe they need to handcuff, through this law, Labour members to the party because they are fearful some may jump ship. They have a large caucus and a Māori caucus that's particularly strong and demanding. It seems they fear another Tariana Turia and want this law as an insurance policy.
