Hon SCOTT SIMPSON (National—Coromandel): Thank you, Madam Chair. It's interesting that Greg O'Connor was the last speaker. People of his generation, and that of the Hon David Parker, will recall that when GST was first introduced into the New Zealand economy, there was a lot of debate and discussion about whether pricing should be GST-inclusive or GST-exclusive in terms of advertising—for instance, supermarkets and any kind of consumer goods and what have you. It's in that regard that I want to speak to the, again, very pragmatic and sensible Supplementary Order Paper (SOP) in the name of my colleague and friend Simeon Brown. It relates to an amendment that he is proposing to clause 7, which would require after section 172 to include the following words: that "For the purposes of the clean vehicle standard, sellers and importers of motor vehicles must include any rebate or charge in the prices of their motor vehicles, including in any advertising."
