Five people were in court charged with shoplifting from The Warehouse.

Overseas tourists appear to be targeting The Warehouse for shoplifting, with a way to steal from the retailer "advertised" online, police say.

Five travellers from overseas have been charged with shoplifting from The Warehouse in Blenheim.

Chloe Mai Lan Cosaert, 20, and Kieran Robert Auguste Debeneit, 20, both French, appeared at the Blenheim District Court on Tuesday jointly charged with stealing clothes and electronic items on January 31.

They did not enter a plea as they hoped to be considered for diversion.

Foreign nationals stealing from The Warehouse appeared to be prevalent in Blenheim and the pair should enter a plea, police prosecutor Sergeant Tom Andrews said. It was not a suitable matter for diversion.

"My understanding is, there was advertising of a way to steal from The Warehouse, and how easy it was, broadcasted on the internet."

There were five people in court on Tuesday charged with shoplifting from The Warehouse, Andrews said.

Cosaert's lawyer Rennie Gould said it would take six weeks to check Cosaert's criminal record in France to prove it was her first offence.

She had already paid reparation to The Warehouse and was happy to pay a donation as further penalty, Gould said.

Judge Tony Zohrab remanded Cosaert and Debeneit at large without plea to February 22 with a condition not to leave the country.

Guilia Alessi, 24, and Roberto Bastoni, 22, both of Italy, admitted stealing a car power inverter from The Warehouse on February 1 at 1.20pm.

They took the inverter from its packaging and hid it in a backpack, purchasing several other items on their way out but failing to pay for the inverter.

It was worth $100.

Their lawyer Rennie Gould said they ran out of money to continue their travels and needed the inverter to charge a phone to contact their families with.

They were convicted and ordered to pay $150 to the store manager as an emotional harm payment, to be put towards a staff social function.

Marius Hayn, 20, of Germany, admitted stealing headphones from The Warehouse on January 8 about 7.10pm.

Police declined to offer diversion.

He was convicted and ordered to pay $150 to the store manager to be put toward a staff social function.

"For the poor people who have to confront people such as yourself," Judge Zohrab said.
