The Wellington hostel fire that killed at least 6 people is officially an arson/homicide investigation, police have confirmed.Inspector Dion Bennett said the death toll is expected to rise, with about 20 people unaccounted for. He didn’t say why police believe the fire was deliberately lit, but a few persons of interest are on their radar. Reports of a separate couch fire at the hostel 2 hours before the deadly blaze are also being investigated. Police were able to enter the Loafers Lodge building to examine the scene for the first time yesterday – a process that will take several days. PM Chris Hipkins said that one of his uni mates was among the missing and that the Kiwi Government would look into whether the country’s building regulations were fit for purpose.
