Campbell Hamish; Tuiono TeanauDr HAMISH CAMPBELL (National—Ilam): I rise to speak in support of the Resource Management (Extended Duration of Coastal Permits for Marine Farms) Amendment Bill in the second reading. I think it's very clear: the objective of this bill is to extend the duration of existing marine farm—and I just will re-emphasise the existing marine farm"—consents to give consent holders certainty and greater confidence to invest in assets and improvement.Now we have heard many many things this afternoon but really I think what I'm going to focus on is kind of the uncertainty that the current aquaculture industry faces. If you were building a house and only had five years to use the land I don't think you'd invest very much in it at all. Even if you had 10 years—Hon David Parker: It's not your land.Dr HAMISH CAMPBELL: —you wouldn't use much. No it's not land. Thank you very much. Space—the space you would use. If you knew you couldn't use a space you wouldn't invest very heavily on it. There's a lot of technology coming in the aquaculture space and we've heard that from some of the previous members.I mean we have to bear in mind—and we've heard about the fin fisheries that the other side want to get rid of. But it was actually—marine farms came around in the late '80s when the wild fish stocks were actually plummeting and since then nearly all the increase in fish protein that we consume has come from aquaculture. If the world wants to continue to eat fish—and I think it's probably a healthy thing to do—we need more aquaculture; we don't need less.If we want to think about it actually farm bivalves—things like oysters and mussels—are probably some of the cleanest source of animal protein we can produce if we're looking at greenhouse gases. Just having a little bit of a look if we want a kilogram of beef it's probably going to emit about 20 kilograms of carbon dioxide. Now that is from a New Zealand farm and that is probably half what the world average actually is. If we look at something like a kilogram of salmon those greenhouse gas emissions are down around to about 6 kilograms and if we look at something like mussels it's probably about 600 grams. That is what we're talking about about being environmentally friendly. So that is just putting a little bit of numbers. We can say we're plundering our resources but actually if we're talking long term this is actually going to be better.Once again I will actually re-emphasise the words "existing consents" because the way some of the other people are speaking in this House you'd think we're turning our whole marine area into aquaculture which is clearly not the case.So this is a very very important bill. We have actually crippled this industry. We've put one foot in a watery grave and the other foot on a banana skin. The thing is as we said it brings in about $763 million a year but that is when we have handicapped this industry. This industry could really do a lot and you know what? We need that money because we need it to have the public services that we want in this country. We want to make sure that our kids can have the absolute best can reach all their aspirations and their potential and that includes having a clean environment. That's why we need to remove the greenhouse gases.Hon Simeon Brown: And they need jobs—our children need jobs.Dr HAMISH CAMPBELL: Absolutely right—our children need jobs. There's over 3000 people employed by this industry and there could be more if we could actually give it the chance.But we also need to think about our challenged coastal communities that need this employment. We could double our exports if we could just give it a chance and that's why I rise to support this bill. I think it is a great bill.ASSISTANT SPEAKER (Teanau Tuiono): The next call is a split call."
