An Otago University lecturer and his students have made more than 600 litres of ethanol-based hand sanitiser in the past two weeks and cannot keep up with demand.
Shyamal Das, a senior lecturer in pharmaceutical science, started making the sanitiser three days before the lockdown began.
He said he initially made 20 litres for the university's School of Pharmacy but he soon found himself supplying the entire university and giving the surplus to essential services in Dunedin such as police and Fire and Emergency.
"There was a big shortage of hand sanitiser in the market. I noticed that we cannot find anything in Dunedin so I decided to prepare it by ourselves," he said.
