Nactional Fist have (over the decades now) campaigned against "Wellington" interfering with the regions. But in practice they are the group that most commonly restricts local democracy. ECAN is one of the most obvious examples but more recently its things like taking away 3 Waters funding, and then in campaigning mode arguing that the answer was they would hold local councils to account for water failures.
They have the corrupt-adjacent fast track legislation reviving zombie projects that locals had already fought and defeated, sacking boards and replacing them with a crony commissioner and now attacks on elected councils. Wellington City Council may well have problems but it is for the people of Wellington who elected that council to do something about it. Not more interference from the Fist.
