Police Minister Judith Collins has been challenged in Parliament over police officers' use of a false drink-drive checkpoint to target elderly euthanasia advocates.
Collins repeatedly said today she was unable to comment on the controversial checkpoint because the officers' actions were under investigation.
Police have referred themselves to the Independent Police Conduct Authority (IPCA) over the matter, in which officers used a booze bus to collect details about people who attended an exit international meeting in Lower Hutt last month.
Act Party leader David Seymour, who wants voluntary euthanasia to be legalised, challenged Collins on the officers' actions during Question Time in Parliament today.
"Does she believe the public have a right to be concerned about police conducting roadside breath screening tests with the intention of collecting personal information for investigations unrelated to road safety?"
