On Saturday, a man with multiple gunshot wounds arrived at Auckland City Hospital after disorder at Point England Reserve.

He later died from his injuries, police said today.

Auckland police launched a homicide investigation after the incident.

Police said they believe those involved are known to each other.

“We would like to reassure people that this was an isolated incident, with no ongoing risk believed to be posed to the wider public,” they said in a statement.

“The Point England community will notice a greater police presence while investigations continue.”
