Narrative:

This problem has been going on for more than 6 yrs. Inbound to ogg, encountered moderate turbulence and occasional severe as we approached south shore of maui. After landing I submitted a pilot report. Upon return to hnl SIGMET, I was in effort for occasional severe turbulence below 8000 south and west all mountains in hawaii. I asked the dispatcher to re-route via north shores of the islands. The dispatcher said cenrap supervisor denied request. I spoke to the supervisor and she denied my request. I asked her to tape our conversation and again asked for a rerte. She denied and became very defensive and uncooperative. I explained that a PIREP and SIGMET were in effect: I also tried to impress upon her the safety issues involved. She continued to deny my request, but either refused or was unable to offer me any explanation. I then told her that to issue the clearance as filed and for me to fly the route would be a clear violation of far. She still refused and claimed that she saw no safety problem. Attempts to contact chief pilot and director of operations was unsuccessful. Made contact with FSDO wkend duty officer. Possible solutions were explored and we agreed that a reasonable solution was to fly to maui at 9000 ft and if visual conditions existed, circle to land. This is what I did. Irregularity report was filed. Callback conversation with reporter revealed the following information: reporter stated the problem began when the center changed procedures 4 yrs ago. It's called flow for the 90's. All traffic is rted over 1 fix. Center is unable to deal with any rerte because of WX. Air carrier companies are meeting with the center to try to resolve problem. Facility says controller workload to rerte is why it is not done.
