While I'm on my feet I will respond to the Hon Michael Woodhouse's point in respect of irrevocable offers. If someone's already in a contract—for example, a long-term agreement for sale and purchase of a section often has a long date by which the vendor has to perfect their subdivision beyond which the agreement can be called off. That sort of agreement is not affected by these changes and the old brightline rules will apply to it, not the new ones.
