Spokesman for the victims group Quake Families, Brian Kennedy, welcomed the findings and said he hoped to see some accountability in the reports.
"The recommendations will be good - it's whether they're taken note of,'' said Mr Kennedy, whose wife Faye died in the CTV Building collapse.
Making buildings able to better withstand earthquakes would now be a focus for designers, he hoped.
"Anyone who designs a building now is going to have that in the back of their mind".
Attorney-General Chris Finlayson and Building and Construction Minister Maurice Williamson also welcomed the report.
Mr Williamson said the recommendations in the report will influence future design and construction practice in Canterbury and throughout New Zealand.
Mr Williamson said the Government will accept all 70 of the findings.
"There is already a comprehensive programme of work underway to address recommendations coming from earlier technical investigations and the expert panel who reviewed the collapse of Christchurch buildings during the 22 February 2011 earthquake.
"The Royal Commission's recommendations generally align with the recommendations made by the Expert Panel.
"Some have already been implemented while others are being worked on or are planned for in the Ministry of Business, Innovation and Employment's Building and Housing Group's three-year work programme," said Mr Williamson.
The ministry is looking at amendments to the Building Code that will improve the performance of commercial buildings in severe earthquakes.
Mr Williamson said the 70 recommendations released today will be used in the redevelopment of the Christchurch CBD.
The final report will be completed by November this year.
Mr Finlayson said the Government expects to issue a full and comprehensive response to the Royal Commission's complete findings early next year.
