Penguins at a New Zealand aquarium are being singled out for their naughtiness.

Keepers of the penguin enclosure at the National Aquarium of New Zealand have decided to name and shame the naughtiest penguins in the colony, whilst also telling visitors what ''crimes'' they have got up to.

A post on their Facebook reads: ''Mr Mac takes the cake (or should we say fish) this month! Can you believe he snatched a fish right out of his girlfriend Lulu's mouth? Taking food from an almost blind penguin - how could you Mr Mac!''

And it was penguin Dora who got the ''good'' award this time around.

The aquarium said: ''Dora was such a trooper at our regular health checks this month. She waddled straight over to the scales and, with a little helping hand and no fuss at all, popped up to be weighed. If only everybody was as compliant on weigh day as Dora!''
