A spat, involving allegations of the manufacture of methamphetamine, has broken out between Housing New Zealand and a paraplegic Mount Maunganui woman.

Karla Webster, who lost the use of her legs in a car accident that also killed her friend in 1998, has until July 10 to vacate her specially modified property in Mount Maunganui.

Mount Maunganui paraplegic woman Karla Webster outside her Patterson Street flat.

'The house that I'm in, they re-gutted the kitchen for me and put in a kitchen bench on hydraulics that goes up and down and they put in a wall oven and converted the bathroom and toilet for me and put in ramps – they've done a good $20,000 worth of work to the house,” she says.

Since the accident Karla has spent time in Otara Spinal Unit, Althorpe Private Hospital, with her brother before moving into the current Patterson Street flat four years ago.

She received a letter from Housing New Zealand in early April advising her she had three months to vacate the flat.

A Tenancy Tribunal ruling a week ago went against her, and now she must leave the premises by July 10.

'I'm pretty gutted – it's perfect for me. They haven't even relocated me – I can apply for another house.

'I lost because like every other landlord apparently, they've got every right to give me a 90 day notice – they don't have to give me a reason if they want the house back.”

Tenancy service general manager Kay Read says Housing New Zealand does not tolerate tenants using its properties for unlawful activity.

'In this case, the tenant breached her tenancy agreement by using her property for possession and supply of cannabis.”

'Tests carried out by the New Zealand Drug Detection Agency also confirmed a positive result for methamphetamine, at levels indicating the property had been used to manufacture the drug.

'As with any chemically contaminated property, it is not safe for the tenant to remain at the property.

'Ms Webster has been advised of this both verbally and in writing, but has chosen to remain at the property.

'We have offered to refer Ms Webster to agencies that can help her find new accommodation, but she has declined.”

Karla says she was convicted on a technicality, and that the cannabis found in the flat was for personal use.

She also denies any knowledge of methamphetamine production and did not know the tests had even taken place.

Karla says there was no mention of methamphetamine production in the Tenancy Tribunal hearing.

Kay says forensic and industrial science specialists will determine whether the property needs to be decontaminated once Karla has left.

Depending on the level of contamination, this can range from industrial cleaning through to having the property demolished.

Between 2006-2011, 26 Housing New Zealand properties, out of a total of 69,000, tested positive for methamphetamine.

In 2009, the corporation won a test case seeking more than $180,000 in damages from tenants who manufactured methamphetamine in a Napier state house. The house was demolished in 2004.

Karla doesn't know what purpose the house will serve once she leaves, and due to a number of complicating factors – including her specially trained dog, her wheelchair and the fact she needs a five year lease on any new flat before ACC will consider modifying it – will be forced to move into a basement apartment.
