Police would like to speak to this man in relation to the theft of a Queen Victoria Diamond Jubilee medal from Aratoi on Wednesday.
A Maori chieftain's heirloom has been stolen from Aratoi Museum in a lunchtime raid, devastating staff.
The silver Queen Victoria Diamond Jubilee medal was stolen from a display cabinet in the museum at about 12.40pm on November 26.
Aratoi director Alice Hutchison said the medal was a collector's item and was a centrepiece of the museum's collection.
She was focusing all her energy to help track down the suspect, she said.
"I'm devastated."
Senior Sergeant Jymahl Glassey said police were reviewing the CCTV footage.
"Someone has entered and removed [the] medal from a display cabinet. It appears they have unscrewed the screws and removed the glass."
The medal was loaned to the museum by the family of Hoani Paraone Tunuiarangi, a notable Wairarapa chief and Volunteer Force captain who travelled to England to take part in Queen Victoria's diamond jubilee celebrations in 1897.
Mr Tunuiarangi was introduced to the Queen and presented with a ceremonial sword inscribed for the occasion and a silver jubilee medal.
Both the medal and the sword were entrusted to the museum in 2003.
Chairman of the Aratoi regional trust Frazer Mailman said the medal was taonga and it was disappointing anyone would stoop to steal it.
"We are very upset, not only for Aratoi and the staff, and the owners of the medal, which was on loan, but for the community as well. What this person has done is take some of the history away for the community."
"It's a significant loss to the family and for the local community and to visitors to the region."
He understood the thief had visited the museum previously and may have used an Allen key to open the cabinet, Mr Mailman said.
The board will meet later this week to discuss security and the possibility of offering a reward for the return of the medal.
