A man whose wife was one of the 115 people killed in the CTV building in the earthquake last February says he may consider legal action against those responsible for its failure.
A Government report has found the building did not meet the required standards when it was built 26 years ago. Neither the walls nor the columns met the relevant standards.
Maan Alkaisi says learning of the building's structural weaknesses has saddened him.
He says if people are found to be responsible in any way for the building's inadequacies, they should be held accountable.
While the report confirmed some of his suspicions, Mr Alkaisi says questions that have been left unanswered - for example, what caused a fatal fire in the building.
He hopes the Royal Commission into the earthquakes will address his questions.
