The New Zealander was twice placed on report in the 14-all draw at Toyota Stadium and was charged by the NRL judiciary on Tuesday with two grade one high-tackle charges.
The first incident occurred in the 13th minute of the clash when the Roosters player made contact with Ben Ross before a second incident involving Jeff Robson in the 63rd minutes of the game.
Each charge carries a separate one-game ban if Waerea-Hargreaves contests and loses but the more likely scenario is Hargreaves missing this weekend's match with South Sydney by taking the early guilty plea on both charges and receiving a one-game suspension from the accumulated points.
Waerea-Hargreaves could escape suspension if he successfully contests both charges or takes the early plea on one and successfully contests the other.
The NRL has given until midday on Wednesday for Waerea-Hargreaves to respond to the charges.
