Police actively working on alleged rugby club fraudster Nicola Flint investigation as more details revealed

Police may be closing in on alleged rugby club fraudster Nicola Flint, nearly six months after she left New Zealand with her family.

Now the country's biggest bank has confirmed it's helping police with their enquiries.

And Newshub has uncovered yet more alleged lies told by Flint.

Nicola Flint told numerous people her late father was an earl and 13th in line to the British throne, and had a French estate.

She once emailed pictures of the property to her mother-in-law in New Zealand, offering the French mansion as a place to stay during their planned holiday in Europe.

Her email said: "Whilst the family are okay with people staying in the house, I am awaiting for official permission to confirm that I have access to the house, as it is currently 'in the care' of the Government, whilst probate and other legal issues are being concluded following my father's death."

But the offer of accommodation was reneged.

"She ended up finding us a flat... in Montmartre. And we stayed in this tiny flat," Newshub was told.

The family recently Google-searched the images on the email.

"Went through each individual photo and it was photos from all different houses," Newshub was told.

Flint said it was not the only estate the family owned.

"When I first met her she said she lived in a house similar to Downton Abbey and they had servants," Newshub was told.

Flint allegedly stole more than $100,000 from a Christchurch rugby club last year, and also used fake and forged documents that claimed she had terminal cancer. She has lied to many close friends and family.

She then left New Zealand and moved back to her native England with her husband and children.

Flint also medically retired from a job at ANZ using fake medical documentation. ANZ confirmed to Newshub this week that they are now helping police with their enquiries.

Newshub understands some medical practitioners are also helping police.

Last month, Flint secretly sold the Christchurch family home for hundreds of thousands of dollars below its capital value.

Sources told Newshub police swooped on the property after it was sold. Police then confirmed to us that they recovered 12 guns and ammunition from a St Albans property.

In another story Flint told her current in-laws her ex-husband was lost at sea, presumed dead. But Newshub's enquiries show her ex is alive and well living in England - which is news to Flint's mother-in-law.

"Bloody hell, I didn't realise he was still alive - I thought he was still fighting with the sharks," she told Newshub.

Newshub has also obtained a copy of what appears to be Flint's CV, which states she has: "Strong competency in business development... driving major sponsorship funding... community grant opportunities."

It also stated that she worked at "HSBC, Europe and Middle East" and was "responsible for writing, reviewing and sanctioning all offshore client related credit and lending applications".

And that she was the "lead cellist London Philharmonic Youth Orchestra" and a "concert level pianist".

The London Philharmonic couldn't confirm this, telling Newshub their records don't go back that far.

HSBC is yet to respond.

Police won't confirm where they are at with the investigation, only that they are actively working on it.

But there is good news for the Flint's dogs, Winnie and Goose, left behind at a Canterbury kennel.

The kennel has confirmed the pooches are now being cared for in a loving home environment, and that Flint's outstanding kennel bills have been paid in full.

But other alleged debts and lies Flint left in New Zealand won't go away quite so easily.
