A man was found dead at the Royal Reserve park in Beauchamp Drive, Massey, around 12.10am.
Detective Inspector Aaron Proctor said a 26-year-old man was arrested this morning and will appear in Waitākere District Court today charged with murder.
“We know this will have been a shock to the community, however we would like to reassure them this appears to be an isolated incident.
Police said they couldn’t release details of the man killed.
“We are continuing to make inquiries, but also want to encourage anyone with information to get in contact with us.
“Even the smallest detail could bring justice for the deceased.”
The whole of Beauchamp Dr in West Auckland is blocked off as a result of the police investigation.
The police cordon extends from Beauchamp Dr to the edge of the playground inside the reserve.
A “specialist search group” police investigation tent is set up at the bottom of the drive and playground and the police cordon was extended earlier in the morning.
Police would like to hear from anyone who was in Royal Reserve park or the wider area, including in and around Reverie Place.
Forensic investigators are taking photos and combing the scene kitted out in boiler suits, masks and gloves.
Two people who live nearby told the Herald they were shocked to hear someone had died in the reserve.
