The Prime Minister has met with the victims' families of the CTV building collapse in Christchurch on Thursday.
PM Jacinda Ardern says she felt a duty of care and that from a pure human perspective it was important to do everything in her power to prevent such a tragedy in the future.
The CTV building collapsed after the February 22, 2011 earthquake, killing 115 people including 65 foreign students. It accounted for the bulk of the quake's 185 deaths.
Ardern gave the families an update on the work the government has been doing, since the Justice Minister Andrew Little met with families in December, which included looking into legislation surrounding the 'year and one day' rule.
The rule, which is explained under the Crimes Act as death to have taken place within a "year and a day" after the defendants' negligent conduct ceased - is an obstacle to prosecution in this case, Crown Law stated last year.
