KiwiNZ: I am not sure if there is already, but if not there should be greater flexibility for those that are self employed. In many cases their income cannot continue if they take time out to serve unlike wage and salary earners. The Justice department can only apply flexibility afforded them by legislation or approved policy.
Changes would probably have to be made in Parliament.
The only flexibility is to defer it to later. Unfortunately for most self-employed "later" is too far in the future to predict so the flexibility is effectively useless to them.
The politicians seem to have missed the "don't work, don't get paid" nature of self-employement.
