An 18-year-old man has been granted interim name suppression when appearing in court charged with murdering 64-year-old Murray Wilkinson at Waihi Beach.
Mr Wilkinson, an expatriate New Zealander who lived in Queensland, was stabbed in the head and neck early on New Year's Day and died two days later in hospital.
Police arrested a Waihi teenager on Tuesday and he appeared in Hamilton District Court on Wednesday, being remanded in custody to appear in Tauranga District Court on Monday.
Detective Inspector Chris Page says the arrest followed "immense support" from the community.
"There is still a lot of work to do in relation to the number of weapons that we have received and some forensic testing will be required to be able to confirm whether we, in fact, have the weapon we are looking for," he told a media conference.
Police still want to hear from anyone who was staying at addresses between 1 and 40 Citrus Ave on the night of December 31.
Mr Wilkinson had been stabbed while investigating a disturbance outside the caravan he and his wife were staying in at the front of a friend's property.
