The 107 Aucklanders who took part in the Lifewise Big Sleepout on July 3 have raised $154,000 to help the homeless. With little more than a sleeping bag and a sheet of cardboard, participants spent the night at the Auckland University of Technology. Temperatures plummeted to just six degrees at midnight. ‘‘I think it was the coldest night that we’d had at a big sleepout in the five years that we’ve been doing this,’’ Lifewise’s Lesley Mynett-Johnson says. Donations are being taken online throughout July at bigsleepout.org.nz.
