Coroner Gordon Matenga's released his report on the death of 75-year-old Henry Bush - who was crushed to death in his car when a brick facade collapsed .
Matenga recommends the report go to Parliament's Transport and Infrastructure Committee - to inform changes to the Building Amendment Bill.
Bruce McEachen's son Matt was killed in similar circumstances - by rubble from the roof of the tattoo parlour he worked in.
He says they point to current loopholes in the legislation which need to be addressed quickly.
