He is calling for the government to ban the online sale and delivery of alcohol during lockdown to prevent harm.
"At a time where the nation is in a state of emergency and under government instruction to isolate at home.
"It is absolutely unacceptable from our point of view to allow the delivery of alcohol to homes that are already under stress."

The Māori Women's Welfare League wants the sale of alcohol to be totally prohibited during lockdown.
The league president, Prue Kapua, said the call should extend to ban supermarkets from selling wine and beer too.
She said the government should be doing everything it can to minimise family harm during isolation.
"We perhaps should be looking at it across the board if we are as a society going to be mindful of the wellbeing of everybody."
Kapua said the situation is not helped by a reduction in available social services for victims of family harm at the moment and a lack of other accommodation options for women and children.
