Police investigating a fatal stabbing in central Auckland believe they may have found the knife used in the killing.
Austin Hemmings, 44, of Devonport, was stabbed to death about 5.30pm on Thursday in Mills Lane while trying to help a woman who had been assaulted. His funeral will be held on Wednesday.
Police say they have found two knives in the Mills Lane area. They being forensically tested and one is believed to be the weapon involved.
Police are also looking for a taxi driver believed to have driven the suspect to south Auckland on the night Mr Hemmings was fatally stabbed.
Detective Senior Sergeant Gerry Whitley says a fare to Mangere or Mangere Bridge may be a crucial part of the puzzle they are piecing together.
A mobile police station has been set up in Mills Lane on Tuesday in the hope of getting more information.
A man, 45, appeared in Auckland District Court on Friday charged with assaulting the woman Mr Hemmings went to help.
The name of the accused is suppressed and police say he will face further charges when he reappears in October.
