When you read the Resource Management Act 1991, the word "effect" has a specific meaning. The term "effect" includes any positive or adverse effect, and it can be temporary or permanent. It can also be a past, present, or future effect.

The word "effect" also refers to any cumulative effect that happens over time or with other effects. This is regardless of how big, strong, long, or often the effect is. You should also consider any potential effect that is very likely to happen, or one that is less likely but could have a big impact.

The meaning of "effect" is important in the Resource Management Act 1991, and it was amended on 7 July 1993, by section 3 of the Resource Management Amendment Act 1993. This amendment changed the way "effect" is defined in the Act. You can find more information about this amendment in the Resource Management Amendment Act 1993.
