Police are now in the final stages of deciding whether to press charges over the collapse of the CTV building during the 2011 Christchurch earthquakes.
The office block pancaked in the February 22 quake, killing 118 people, and the outcome of an investigation will determine whether anyone should be held criminally culpable for its collapse.
Police say a legal review by Crown Law has been completed, following an earlier review by the Christchurch Crown Solicitor.
"As we have previously stated this has been a very complex, technical investigation, involving a range of expert advice to consider," says Detective Superintendent Peter Read.
"The decision will be ultimately made in accordance with the Solicitor General's prosecution guidelines, which determines every prosecution decision by police.
"While police are unable to pre-empt what the decision will be at this time, we can say that the issues before us are finely balanced."
A Royal Commission of Inquiry found flaws in the building's design and construction, but nobody has yet been held responsible.
Critical elements of the building's structure have been physically re-built and tested as part of the investigation, along with specialist engineers examining the site and foundations.
Police haven't given a specific date on when their decision will be announced, but have said it will be communicated to the families first.
ChristChurch Cathedral
The announcement from Police comes nearly a month after the decision was made to rebuild the ChristChurch Cathedral.
The decision was made at a meeting of 220 members of the Anglican Church's synod.
With an estimated restoration cost of more than $104 million, the Government is expected to pass legislation that would allow the Anglican Church to fast-track the reinstatement.
