Well, I guess we're not going to get anything more than this latest from NZ Herald

Looks like they hit a runway light at some stage during their departure. I wonder if the crew knew they had it or if a subsequent routine runway inspection or ATC observation identified a 'missing' light?. The latter case might explain the delay in returning to Christchurch perhaps? Anyway, no biggy ie, no one hurt and no significant damage it seems but interesting given we also have the AA321 incident taken out a runway remaining sign on departure to show perhaps what could have happened.
