It is understood Harrison apologised to the Hawks franchise and offered to pay for the repairs, including damage to a shower block wall.
But it was further agony for the southerners, who were probably still trying to exorcise the Hawks' demons when they succumbed 108-101 on the other side of the Manawatu Gorge the following day. The Rams had beaten the Jets 101-92 in Christchurch in round four for their only victory in six outings.
While it is fair to assume that sort of aggressive behaviour is unacceptable, on the flip side one can also perceive it as a team showing passion.
Only the parochial Cantabrians would have given the Rams a chance of winning that day but they showed they are capable of slipping on the knuckle dusters in the driving lanes when push comes to shove.
All that, of course, isn't lost on Hawks captain Paora Winitana, who played for the defunct Christchurch Cougars for two seasons (2009-10) before the 2011 earthquake robbed them of a presence in the Bartercard National Basketball League (NBL).
"Sure, they'll [Rams] be ready and they'll be out to make a statement," the veteran Hawks swingman says but adds his men are looking forward to tomorrow's 7pm tip off.
"It'll be a pretty exciting game both on and off the court ... so we'd not have it any other way," says the 37-year-old who accepts they let their guard down at the PG Arena to let the Rams get back into the game.
The Hawks, having seven wins from nine games and undefeated in five games at home, squandered a 46-36 lead at halftime when the Rams fired up the kiln (37-14) in the third spell.
Winitana says the Hawks are a third/fourth quarter side but they have scrutinised the match videotape to identify areas they need to patch up to avoid a repeat.
"When a team is on the brink of collapse then we should be putting them away because that's what champion sides do if they want to go to make it to the playoffs but we didn't do that," the former Tall Black and Adelaide 36ers player lamented.
He is mindful the Cantabrians are a passionate province when it comes to sport and have dug deep to overcome the adversity of the quake to be back in the NBL.
"My wife and kids stayed there, too," says the Mormon bishop who returned with his family to Napier after the tragedy.
However, he hastens to add, he and the Hawks have no qualms about playing at Cowles Stadium or any other venue around the country adopting a "fortress-like" mentality.
"I don't care when and where we play because all the courts will be the same," he says, aware people are talking about how the PG Arena crowd last Friday night was humming.
"It was just another game and we closed it up - it was business as usual."
Ex-Hawk and veteran point guard Kench, Rogers and import shooting guard Glen Dandridge are the pivotal playmakers with recent signing Marcel Jones but Winitana reckons the challenge for the new franchise is to crochet the threads of youth into a cohesive unit.
"It's tough when quality teams are losing by small margins."
The Hawks have had their fair share this season, losing in overtime to the Pacific Jewellers Saints in Wellington (93-91, April 2) in their opener before succumbing to the OceanaGold Nuggets (97-91 April 25) in similar fashion in their double header of the Deep South.
That mettle will come under test again because the Hawks must hop a plane back to Napier to host the Saints at the PG Arena on Saturday at 7pm in another double header.
The "tight group" have their share of nigglies but import forward Kareem Johnson and bench forward Darryl Jones are still turning out to scrimmages.
That, Winitana, believes, is a testimony to a great pre-season and coach Tab Baldwin putting a "great ship together".
Last year's mediocrity has left a bad taste in their mouths and gargling that out will be some what therapeutic.
