A further picture was posted of the golden kiwi pendant handcrafted by goldsmith Jens Hansen and given to the Duchess on behalf of the city of Nelson.
"During November's visit to New Zealand, The Duchess of Cornwall was given this beautiful Kiwi pendant. #WaitangiDay."

"The pendant was crafted by @the--ringmaker, and presented to HRH on behalf of the town of Nelson."
Last year the celebrated goldsmith said on his Facebook page he would be keeping an eye out for when the Duchess of Cornwall wore the necklace.
