A report commissioned by the Department of Building and Housing highlighted weaknesses in the concrete columns that supported the six-storey structure, as well as an asymmetrical layout of its shear walls.
It collapsed within seconds when the magnitude 6.3 quake hit on February 22, killing 115 people, including several of Mr Yardley's friends and colleagues.
He said: "This report confirms some of our own doubts we had over the structural integrity of the building and why it made such crazy noises and had that sense of fragility to it leading up to February 22."
While the report fails to attribute blame for the building's weaknesses, Mr Yardley hopes that if people are found to be accountable then they should face charges.
"I'm not surprised the report is so damning. I believe that if there is people to be held accountable, then that should happen," Mr Yardley told APNZ.
"I'm pleased the police have decided to instigate their own investigations so promptly. There seems to me to be two areas of investigation: whether there was gross negligence on the part of the building's engineers, and whether there was gross negligence on behalf of the city council by signing off those plans."
With the earthquake anniversary approaching, and the Royal Commission of Inquiry into the building's failure still to come, Mr Yardley said "closure" for many families was still "a fair way off."
However, the broadcaster said families should "take heart" from the comprehensive and prolonged investigations: "It's very dignified and very valuable."
