give them back before you suffer

My advice for these thieves is give these taonga back.

"Southland Museum and Art Gallery in Invercargill has confirmed six Maori stone artefacts have gone missing and a police inquiry is under way.

Manager Gael Ramsay yesterday said the artefacts consisted of adzes and other stone tools including some made from greenstone.

She valued the collection at "up to $1000 at the maximum"."

The monetary value doesn't matter - it's the tapu you have to worry about. Give them back.
