Kyle Brandon Jack-Midgley, 27, was in the CTV building when it collapsed during the earthquake.
His brother returned from Brisbane the day after the quake to help search for him.
Kyle's brother, Ryan Jack-Midgley, posted on his Facebook page during the week of the earthquake: "Kyle, I'm coming to find you and I expect you to be the first one to tell me off for crying when I do ... wish me luck people."
But on February 25, hope was mingled with frustration when Ryan posted: "Without at all eliminating hope, today was a bad day. We were told that there is still a chance survivors could be found in the CTV building and as we know, if anyone was gonna be that survivor he'd be my brother."
