There has been a development in the police investigation into the death of expatriate New Zealander Murray Wilkinson in Waihi Beach.
Police have called a media conference for tomorrow.
Mr Wilkinson, a 64-year-old living in Queensland, stepped outside the caravan he was staying in early on Tuesday morning to investigate a noise, and was stabbed in the neck and head.
The offender fled the scene when neighbours heard a disturbance, and Mr Wilkinson was taken to Waikato Hospital where he died on Thursday.
Waihi police asked for New Year's Eve revellers to supply their festive photographs in the hope police could identify the assailant.
