"An officer is due to speak to officials at St Helens (on Monday) and will also be in consultation with the RFL and if appropriate the CPS in order to decide what, if any, action will be taken," said a spokesman.
"It is not expected that a final decision will be made today in relation to whether or not there will be any further police involvement."
Hohaia has also been charged over the incident, although with a lesser Grade B offence for allegedly using a forearm to the face of Flower.
Five British brain explosions
Flower's attack on Hohaia in only the second minute completely overshadowed Saints' 14-6 victory over the defending champions at Old Trafford on Saturday, with the prop's double punch receiving widespread criticism.
Indeed, he was still trending on Twitter in the United Kingdom on Sunday morning and his actions prompted the Warriors to issue a press release in which Flower, coach Shaun Wane and chairman Ian Lenagan all apologised for the incident which led to the Wales international making history by becoming the first player to be sent off in a Super League grand final.
His charge carries a minimum eight-game match ban although the RFL could opt to give the 26-year-old an even longer suspension.
Hohaia, unlike Flower, has the option of submitting an early guilty plea by Tuesday night NZT, with his charge carrying a ban of between one and two matches.
The 31-year-old instigated proceedings and Flower took exception to an apparent use of a forearm by blatantly punching the former New Zealand international to the ground with a right hook before landing another punch to the face as his opponent lay motionless on the pitch.
While Hohaia appeared to bear no grudges towards Flower, saying "people do some things they regret", Saints chief executive Mike Rush is keen for normal disciplinary procedure to take place.
