The union had requested independent assistance from New Zealand Rugby.
"When originally filed, the complaint could not be progressed when alleged offenders could not be identified in the required 48-hour post-game timeframe," Connors said.
"Judicial advice provided to the union stated that the complaint could not be accepted outside the lodgment window."
Connors said the Coast union and NZR had been in discussions over the past week, following ongoing public debate.
"South Westland have asked for exceptional circumstances to apply in this case, and given the intense public interest, and in the interests of the game, we have agreed.
"Given the time lapse since the original alleged incident, the public scrutiny of this issue, and to give all parties confidence in the process, while allowing us to focus on delivering the game locally, we have asked New Zealand Rugby for assistance in investigating the complaint. We are grateful to New Zealand Rugby for that support.
"It is important to state publicly that West Coast rugby does not tolerate racial or any kind of discrimination or abuse. There is no room in the game for this kind of behaviour, and I urge everyone involved in the game to take responsibility to ensuring it is not tolerated," Mr Connors said.
South Westland Rugby Club's secretary Paddy Kennedy, of Whataroa, said this morning that until the matter was resolved the club would prefer not to comment.
"The club, however, does not have a problem with the Kiwi Rugby Club as a whole. We even have under-14 rugby players playing for the Kiwi under-14 team," he said.
Kennedy said he was disappointed it had taken so long for something to be done about the issue, but was "pleased it was finally being investigated".
