As an essay style, make an argumentative piece on the issues regarding section 30 of the New Zealand Evidence Act 2006, in particular the reason for amendment of section 30(3) to clarify how the "seriousness" of an offence is to be determined and whether this factor favours exclusion or admission; whether the availability of alternative techniques favours admission or exclusion; and whether the absence of alternative techniques has any bearing on the section 30(2) balancing exercise.
