NZ pipe is a pain in the butt, Don't cut corners by using downpipe, pressure pipe is expensive but its worth it.
oh and guys don't tell him to use sch40. Not every country uses it. He'll end up spending a few weeks searching for it. cheeseclip pressure pipe in New Zealand is labled 'PNXX' the xx is the pressure rating in BAR. e.g 'PN18' on the pipe means 'Pressure Number 18 BAR' which is about 260psi.
