Labour Party leader Phil Goff says the time has come to boost security in taxis and consider protective shields between drivers and their passengers.
Mr Goff on Monday visited the family of Hiren Mohini, 39, an Auckland taxi driver who died after being stabbed in his cab at about 1.30am on Sunday.
The Mount Roskill MP also met a group of taxi drivers who worked with Mr Mohini.
Mr Goff says they told him surveillance cameras and panic buttons are not enough, and they want a mandatory requirement for protective shielding in cars.
He says it's sad it's come to this in New Zealand, but their concerns must be taken on board.
