However, his recommendation there should be an investigation into whether all clothing should carry a fire safety rating has not been taken up.
Mr Crerar made the recommendations in his findings on the death in Alexandra in June 2008 of 86-year-old Ethel Watt, who died after an lpg heater set her clothing alight.
About the same time as he made his recommendation public, a Dannevirke woman in her 90s died when her dressing gown caught fire while she was warming clothes on a gas heater.
In October 2008, Dunedin woman Florence Pearson (80) died in Dunedin Hospital from burns after a similar incident.
Last week, Mr Crerar warned of the dangers of using gas burners in enclosed areas after the death of Rex Hodgetts (68), who died of carbon monoxide poisoning in his caravan near Te Anau in June last year.
As well as the review of the safety of lpg-fired cabinet heaters with the view to phasing them out and banning them, Mr Crerar recommended in his finding on Mrs Watt's death an urgent and comprehensive investigation into the flammability of clothing - particularly nightwear - on the basis that all clothing carries a fire safety rating.
A Ministry of Consumer Affairs spokeswoman said the ministry decided against the investigation because it believed the labelling of all clothing with a fire rating would not achieve the coroner's desired outcome.
Almost all everyday clothing was flammable when it came into direct contact with a heat source and there was a wide range of clothing available on the market.
"For example, the ministry questions the usefulness of labelling, for example, swimwear, business suits and eveningwear."
Education on general fire safety was more likely to be effective.
This was done by the New Zealand Fire Service, which ran fire safety public awareness campaigns, including the "Keep a Metre from the Heater" message.
Labelling of children's nightwear is mandatory, with labels alerting caregivers to the dangers of flammability and to the advantages of wearing appropriately styled nightwear to reduce the risk of burning.
Mr Crerar's other recommendation after Mrs Watt's death, that the safety of lpg cabinet heaters be investigated, is being followed up.
The Ministry of Economic Development, Energy Safety appointed the New Zealand Institute of Economy Research to undertake a major review of lpg heater safety last year.
The review will look at whether they remain a suitable means of heating in New Zealand.
The institute was reviewing literature and seeking input from a wide range of stakeholders including relevant industry, safety, health, environment and research organisations, a spokeswoman said.
The review would be completed later this year.
Stand-alone gas heaters are already outlawed in Australia.
There are about 500,000 of them in New Zealand.
