BARBARA KURIGER (National—Taranaki - King Country): Thank you, Madam Chair. In light of the explanation that the Minister, the Hon Damien O'Connor, just has given around a letter that he thought was a bit weak in terms of whether people could dig in post holes and other relatively minor things, I've actually got two questions in relation to what he said. One of those is: why did they not just actually put that in a regulation, to say that was a permitted activity, instead of saying that someone could actually just withdraw the letter at some point in time?
