A woman injured while playing roller derby lied to ACC and now may have to pay back the $82,000 she received.

Hastings woman Kellie Louisa Mary Hoy, 34, lodged a claim with the Accident Compensation Corporation after injuring both her knees while playing roller derby on October 5, 2014.

Hoy said she was unable to complete home and community tasks which included the full time care of her three children.

The corporation accepted her claim and also agreed to provide home and community support services for her children, which she claimed were in her fulltime care.

From December, 2014, Hoy received 61 hours care per week during the school holiday periods and 48.5 hours per week during the school term.

STUFF ACC is seeking more than $80,000 in reparations from Hoy.

Between January 2015 and March 2016 Hoy presented 14 weekly forms to ACC, signed by her and her carer showing the support services she had received.

In frequent discussions with ACC staff Hoy referred to the needs of her two sons, whom she said lived with her and attended a Hastings primary school.

When the corporation investigated Hoy in 2016 it discovered she did not have parental custody of the boys, and that they had been living with their respective fathers since prior to Hoy's roller derby accident.

FAIRFAX NZ Hoy appeared in Hastings District Court on Tuesday.

Both of the boys' fathers confirmed that they had court ordered parental custody orders of their sons which were obtained prior to Hoy's accident, and both boys were enrolled at schools in Taranaki. They had never attended schools in Hastings.

But they had visited Hoy at her home during the Christmas school holiday period in 2014/2015, and it was during this visit that Hoy arranged for her two "needs based" assessments.

ACC said Hoy did this to support her misrepresentation that they were in her care.

The corporation also discovered that care had not been provided despite Hoy's claims that it had been, and that she had forged the signature of the carer listed on the forms.

During the relevant periods, Hoy personally received $16,631.83 from ACC. The corporation paid a further $65,296.60 to Healthcare NZ to carry out the services at Hoy's house.

ACC is seeking the full $81,928.43 in reparation from Hoy.

Hoy appeared in Hastings District Court on Tuesday and pleaded guilty to representative charges of obtaining by deception, dishonestly using a document and using forged documents.

She was remanded on bail and will be sentenced next month.
