The Honourary Consul in Cebu is Moya Jackson, and she is most definately, as Rory points out, able to convert the CNI. Appointments with her are necessary, and she does go out of the country on occasions.
She operates out of the club house on her subdivision, which is near Banilad, approximately 10 minutes from the Mactan Bridge in Cebu. Most taxi drivers known the subdivision, if not its on google maps so you can print it out.
