President Michael D Higgins arrived in New Zealand on Tuesday and met with newly sworn-in Prime Minister Jacinda Ardern, beginning his week-long visit.
President Higgins laid a wreath paying respect to the two Irish nationals and other 183 victims who died in the eartquake.
Irish national John Joseph O'Connor, 40, died in the Pyne Gould Cooperation building that collapsed to during the February 22 earthquake.
Media reported at the time Mr O'Connor arrived in New Zealand in September 2010 to start a new life in Christchurch.
Irish-born Owen McKenna, 40, was a father of two and it has been reported he moved to New Zealand six years before the quake.
The family of both Mr O'Connor and Mr McKenna are expected to visit the memorial site with the President.
The Christchurch Earthquake National Memorial, which remembers all victims of the 2011 disaster, was unveiled earlier this year on the sixth anniversary of the quakes.
The opening was attended by then Prime Minister Bill English, former Christchurch Mayor Sir Bob Parker and other dignitaries including families of victims from overseas.
