Transport Minister Steven Joyce says he will talk to the Department of Labour and the taxi industry about making cameras mandatory for taxis.
Mr Joyce told Morning Report he expects to discuss the possibility of precautions to better protect drivers within the month.
However, he said there is a lot of disagreement about what is the best course of action.
Hiren Mohini, 39, a father of two, was fatally stabbed after picking up a fare in Auckland at about 1.20am on Sunday.
The Taxi Federation says the killing could have been prevented.
The federation says it suggested installing cameras in cabs to the government after the death of a driver in Christchurch more than a year ago.
Executive director Tim Reddish told Morning Report it's disappointing the recommendation was not picked up.
He told the programme that such cameras in Australia, were paid-for by the government.
However, Mr Reddish says some companies have already installed cameras off their own bat without a mandate.
Police are seeking a man seen running from the crashed taxi in Mount Eden.
He is described as dark-skinned, of slim build, with long greasy hair, and in his mid to late 20s.
