New Zealand Homes Compared to Refugee Camp Huts

Following on from Sunday's article about poor standards in New Zealand's homes, I came across this article in Scoop and thought it may be worthwhile mentioning it here because it helps to demonstrate just how serious and widespread this problem is.

According to a health expert 3 out of 4 homes in some regions of New Zealand were so cold, damp and mouldy that they were on a par with refugee camp huts....

"At a workshop in Wellington yesterday on the health effects of leaky buildings, Associate Professor Jeroen Douwes of Massey University cited a 2005 study, which found mould in 75 per cent of the 1310 households surveyed.

"This is comparable to a study of Palestinian refugee camps, where the rate was 78 per cent."

Nationally, about 35 per cent of New Zealand households report mould in one or more rooms, compared with 18 per cent in Europe.

A survey by Otago University public health researchers of 33 peer-reviewed studies found exposure to damp and mould raised the risk for respiratory problems -wheezing, coughing and asthma - by 30 per cent to 50 per cent.

Conservative estimates put the direct health costs of leaky buildings in New Zealand at $61 million a year.

Public awareness of respiratory problems associated with damp houses remained low, he said.

"This issue affects potentially tens of millions of people worldwide, and there is a big case for more interventions and research."

University of Otago public health researcher Professor Philippa Howden-Chapman, who chaired the workshop, said New Zealand's high asthma rate could well be related to the incidence of damp houses.

Up to one in five New Zealanders suffer the chronic and sometimes life-threatening respiratory condition. Wellington's Asthma Research Group has found that asthmatics allergic to mould had much more severe symptoms, and were almost twice as likely to end up in intensive care...."

Health Ruined in Quarter Million NZ Homes

"A quarter of a million homes are so cold, damp and poorly built they are causing serious health problems, according to a significant new study.

The problem with the houses - which are poorly insulated, some with black mould and potentially toxic air quality - could cost more than $20 billion to put right, say report authors.

Both old and new homes affected

It is not just a problem with old homes. Many new homes and renovated homes lack adequate insulation, heating, ventilation and double-glazing, as builders and landlords invest their money instead in superficial improvements to increase houses' value.

The New Zealand Business Council for Sustainable Development, which commissioned the survey of 3500 households, says the country is suffering a "massive" housing problem and it has called for law changes to bring homes up to scratch.

Respondents said they and their children suffered from a wide range of illnesses, including sinus problems, mould allergies, asthma, bronchitis and pneumonia, caused by damp and badly insulated homes.

Newcomers say 'they've never been colder in homes'

Business Council chief executive Peter Neilson says, "Talk to anyone coming to New Zealand and they say they have never been colder in homes."

The problem has been made worse by rising electricity costs. People responding to the survey said they had been forced to move into the lounge during winter to keep warm; and mould and damp had caused their children to be repeatedly admitted to hospital with respiratory and other health problems.

Demolition For House That Leaks Like a Sieve

Source: NZ Herald, Thurs 4 Sept 2008

A migrant family are so disillusioned with their big house in the Auckland suburb of Lynfield that they are demolishing it. The large 1980s seaside place had many defects and faults, including leaks. The family came here from Taiwan last decade but are so disheartened after years of enduring the house that they have decided to start again........

The 255sq m house was badly designed, wet and cold, they said. Problems were so widespread that it was not even worth removing the house from the site for resale.......

They said none of their windows had flashings to keep out rain. Nor were the walls insulated, which meant the place was freezing. The house was oriented towards the seaward side and the prevailing weather so water came into the lounge and the largest bedroom through windows. But because the house was built in the 1980s, the family had no legal redress via the state-funded system which helps leaky-home owners. The house was not eligible for a weathertightness assessment or claim. The Government bans owners of houses built more than a decade ago from using its leaky building service, which offers free house inspections, written reports on defects and dispute negotiation, mediation or adjudication to resolve problems. "It was not built very nicely," said one of the house's residents yesterday, adding that her family did not initially know enough about the system to commission a building inspector's report before they bought it in the 1990s. "We ... just thought it was a nice area," she said. It was only when a family member met a builder that they discovered the extent of the problem. QV has the house listed as being worth $600,000: $310,000 for the house and $290,000 for the large site.

The Problems Migrants Encounter with Housing

One of the most frequent problems that migrants from developed countries have is with the condition of the housing stock in New Zealand. Much of it is wooden framed, ranging from old Kauri villas to mansions and there are often problems associated with dampness, lack of adequate heating and poor insulation.

There has been a lot of coverage in recent years of a phenomenon called "leaky homes syndrome," it's just another way of describing weather tightness issues and it affects all sorts of buildings - right through from apartment blocks, to townhouses and million dollar homes. For more information see http://www.nailed.co.nz/The_Problem_Explained_943.aspx

If you are thinking about purchasing a property in New Zealand be sure to have a full and proper inspection carried out and make it a condition of the sale that the report be satisfactory.


Most of the houses are timber framed with a skin to keep the weather out - this could be comprised of overlapping boards, plywood, thin brick veneer, metal sheets, plaster or other materials. In older houses there is often no insulation in either the external walls or roof voids, this can cause problems with heat retention during the winter, or over-heating during the summer. Condensation on cold external surfaces is also a problem and this can lead to fungal growth and unhealthy living conditions.

Many houses are built on piles which are usually wooden and can be prone to rot, suspended floors are often uninsulated and draughty.

Problems such as these have resulted in changes being made to the building code to ensure that adequate insulation and, where needed, double glazing is fitted as standard to new homes. However, despite the low winter temperatures in some parts of New Zealand there is seldom any provision for heating other than an open fire or wood burner. Some home owners are installing heat pumps (a type of electric fan heater) but these can be expensive to buy, fit and operate. Heat pumps may also be used to dehumidify and cool the air.

New Zealand has the second highest prevalence of asthma in the world and it is thought that mold spores in damp homes, dust mites and smoke from wood fires are three triggers for the disease.

What can you do?

• If you're buying a house have it properly surveyed and if necessary set aside money to bring the house up to a standard that you are comfortable with. A house that faces north is desirable because of the amount of solar gain it will accumulate during the winter. Be wary of houses that are in valleys or shielded in some way from the winter sun.
  

• If you're renting look very carefully for signs of damp or mold growth, check around window openings, the edges of carpets, in closets and linen cupboards. Also look for signs of water penetration and ask what type of insulation is present in the property. You will need to think about how you are going to heat the house in winter and whether or not to buy a dehumidifier.
