"Karma will come back on them. So I feel quite sorry for the person that's stolen it, because you can't do that, because it's Māori. Karma will come back on them really badly."
Smith-Craig said she was overwhelmed with the generosity from the community with some saying if she felt differently about the replacement, they would still provide her with one.
"I just hope if it does get returned that it's still in one piece. If someone cuts it up and make any pieces out of it and sell them, they're the ones who will have bad luck and they won't even realise.
"They could be a given to a child, a baby, it could even come back to one of my family and that's the tragic thing of it all."

"We all wanted to rub it and place our hands on it, so much love went into it, when we held it, was like holding him."
Although the greenstone was taken the Sunday before Christmas, Smith-Craig said it hasn't hindered anyone from giving up the search.
"My son told me there's about 8000 seekers looking for it, he's a prison warden so even the prisoners are asking 'Sir have you got the greenstone back yet?' So a lot of people have been asking."
The matter has been reported to police.
