The injured man walked across the street and sat down in front of a shop.
The streets were really busy at the time of the attack because it was a Saturday morning, the local owner said.
“These people have no fear of the law or consequences, it’s terrifying.”
He said he went to speak to the owners of the store after the incident and said they were “very shaken.”
“We are so afraid these things are happening in both the day and night, who’s next.”
A member of the public on the street at the time said they saw shop workers pouring water on the blood that was left on the footpath.
The injured person was then taken to hospital with moderate injuries, police said.
Police say enquiries are ongoing to find the attackers and a scene examination is due to take place today.
Police stood down Hato Hone St John crews after they were notified of the incident because they were not required.
