3News reported that Aca, a former police officer in Fiji, wants Canterbury Rugby Union to find the spectators who yelled the abuse and take action against them.
Yesterday Canterbury Rugby Union (CRU) community rugby general manager Tim Gilkison said the union's immediate focus was on trying to find the identity of who was responsible for the comments.
"We're trying to establish whether we can identify [those responsible] through any sources that we've got, like footage of that fixture."
Lincoln University was conducting its own investigation and Dr John Hay, Interim Vice-Chancellor of Lincoln University, said they were of the understanding that it was member of the public standing on the grass embankment that made the racially abusive comments.
"Lincoln University in no way condones behaviour of this kind in any sporting code and is saddened to hear that this occurred at the rugby match.
"The University will work with the Canterbury Rugby Football Union, as well as conducting our own internal investigation."
