I know in clause 95, in subclause 2(c), it says that "the physical force used is reasonable and proportionate in the circumstances", and also in the select committee, we did define what physical force actually means, but we know that children have different kinds of strengths, especially children that have special needs. So how will a grown-up understand what reasonable and proportionate force means for that child? We are talking about children that are of a very young age, from year 5 to older ages in schools. So I have a concern about this, because we have anti-smacking legislation in New Zealand, and I know this is not smacking, but parents cannot use force which can be seen as smacking. But here I know that the force is only to be used to stop any—as we have defined in the select committee process—bodily movement that can cause any kind of harm to that student or anyone else, but it's a fine, fine line.
