I think this will be more accurate, although a short term increase should not necessarily mean an increase in payments. There needs to be context around the situation and fairness to the person earning the income.

Do you agree with this comment?
Yes. As I would like to study at some period to give me more career options. At this rate I'll be stuck working weekends and nights just to keep up with child support payments.
I could see value in this except when the paying parent stops paying and then skips overseas as they then have no short term income history in new zealand and could say they earnt nothing while overseas. I would propose that the last earning year available for them would then be used.
I think 3-6 months is sufficient. Frequent reviews/changes throughout the year will be difficult for both parents.
I think 3-12 months is sufficient. While I ensure that I do not miss payments, I do also find dealing with support changes and communications stressful, given sensitive personal circumstances (which are private to my family and I would not wish to share with an employer).
