Aircraft just took radar handoff from sector 10 and aircraft checked in climbing.  Aircraft was observed turning south bound.  I observed the aircraft about 1 mile west of the flight plan route after the turn climbing thru 114 on the way to cruise altitude but in the 120 MVA area due to the deviation west of course.  I advised the aircraft that he was right of course but did not issue a low alt alert as they were already climbing thru 120 and issued a heading of 180 as the aircraft climbed thru 120 above the MVA.  The crew then advised me that they were on a 180 heading and then said that they were direct to a waypoint which is not on their flight plan.  I called their next sector and asked them if they had issued a clearance to the waypoint and they confirmed that they did not.  I think the pilot may have been anticipating a turn toward the waypoint and did so in advance of a clearance there by violating the 120 MVA over Haleakala.I'm not sure; this was more of a pilot action situation.
A ZHN Controller reported an aircraft deviated from the filed route while climbing to an enroute altitude and violated the ZHN Haleakala 12;000 foot MVA. The Controller did not issue a Low Altitude Alert.
