A QUEENSLAND man stabbed outside his caravan in Waihi Beach, New Zealand early on New Year's Day has died in hospital.
Waihi police have now launched a murder investigation.
Police have named the 64-year-old victim as Robert Wilkinson.
Police are still hunting for the offender, who fled the scene when neighbours heard a disturbance.
The weapon had not yet been found, and police were asking witnesses to come forward.
Checkpoints were set up at Waihi exit-points yesterday for police to talk to holidaymakers as they left the area.
Police have also asked New Year's Eve partygoers to supply their festive photographs, in the hope the pictures identify the attacker.
"We're still very keen to hear from anyone who may have taken images on their cell-phones, iPads, iPods or other technology of people celebrating New Year's around the surf club, camping ground, Beach Rd, Hinemoa Rd and Oceanview Rd between 12.30am and 1.30am on that day,'' Eastern Waikato Area Commander, Inspector Dana McDonald said.
"If you have such images we'd like you to email them to police, along with your consent for us to use them, to our investigation team at Thames@police.govt.nz.''
Mr McDonald said given the advantages of modern technology it wasn't inconceivable that with the public behind them, police could identify through images provided from the public, the majority of people present in the area around the time of the attack.
When the attack occurred, officers were moving on large numbers of mostly young people from the area around the surf club, the motor camp, Beach Rd and Ocean View Rd.
Waihi Beach's normal population is about 3000 but swelled to 16,000 over the festive period.
Mr McDonald appealed to the attacker to give himself up.
