If you look at a law called the Local Government Act 1974, you will find a part that was called section 534. This section was about when an advance is not a charge on land, but it is no longer part of the law. You can find out more about what happened to this section by looking at the Energy Companies Act 1992, which is available at https://legislation.govt.nz/act/public/1986/0120/latest/link.aspx?id=DLM268381. This change happened on 7 October 1994.
