Chronic fraudster Tina Maire Leigh is in custody for sentence after admitting another 51 charges.

The 23-year-old eft-pos scammer gets a kick out of her well practised routine and cannot seem to help herself.

It has already meant jail time, and now it will mean more. When she pleaded guilty to the latest list of charges, Judge Raoul Neave remanded her in custody to September 21 for a Christchurch District Court sentencing.

A report on her suitability for home detention will be included in the pre-sentence report but that outcome seems unlikely for the young repeat offender.

She has already been in custody for months in the lead up to her guilty pleas at a pre-trial conference session.

Leigh pleaded guilty to 12 charges of computer crime, 27 of obtaining money or goods by deception, four of dishonestly using a document, two of burglary, one theft and two shoplifting, one forgery, using offensive language, and breaching the release conditions of her previous prison term.

There was a two year six month term imposed in 2007 for dishonestly using a document, causing loss by deception, obtaining money or goods by deception, burglary, and aggravated robbery.

At the time of that sentencing, her defence counsel Tony Greig said: "There are clearly a lot of issues in this young lady's life and it is a shame that she has not yet had the courage to deal with them."

The judge who jailed her then - the same one who accepted her latest lot of guilty pleas - noted that Leigh lacked insight, and showed no willingness to change her behaviour.

Her time in custody on remand, and in prison, will at least give retailers another break from her activities.

She does a very slick routine with an eft-pos machine when she goes into a shop as a customer.

She manipulates the eft-pos machine and pretends to phone her bank to put the shopkeeper in a position of leaving her with the goods and a refund.
