With a general shortage of match officials, the sideline umpires were provided by the two teams in the match, Mr Tamati understood.
New Zealand Rugby League chief executive Alex Hayton was at a conference and unavailable to be contacted yesterday but a spokesman in Auckland said the NZRL would work with the Hawke's Bay league and family of Miss Waikato, and was waiting until it had more details from Hawke's Bay.
He said it was "very traumatic" for everyone involved and the league would support where it could, though it was unclear whether the League 4 Life Foundation, set up to help struggling families of aspiring players could be involved.
Meanwhile, Mr Tamati's brother, former Kiwis rugby league great Kevin Tamati, who was RLHB chairman when he left to live in Queensland about 18 months ago is expected back in Hawke's Bay this week.
Tributes and messages of condolence for Miss Waikato and family flooded facebook pages yesterday, with well over 200 posted by late afternoon.
