"The two offenders have tried to provoke the victims into a fight," Baldwin said.
Baldwin said police needed the public's help to track down the offenders and solve this unprovoked, senseless and unnecessary attack.
Both offenders are described as being of Pacific Island origin, heavy built and aged between 20 and 35. One was wearing a red T-shirt and had long hair, possibly with braids and the other was sporting a black T-shirt.
Police wanted to hear from anyone who were in the area at the time of the attacks.
"Someone will know who these men are and they need to do the right thing and contact us.
"We would remind everyone that anyone found to be carrying a knife or any weapon is breaking the law and could face prosecution."
