The published information concerning VFR Operations in areas such as Mt Cook, Franz Josef/Fox Glacier, Milford Sound. Mt Ruapehu, Rotorua and other "Tourist designated areas" should be revised and expanded to give all pilots ready access to as much relevant information as practicable regarding items such as promulgated flight routes, designated Reporting Points, minimum heights above recognised geographic features and the specific detail regarding procedures followed by local operators in the particular area, in addition to the requirement concerning radio frequencies to be used or monitored. Example of suitably concise radio communication should also be included to minimise "radio clutter" by pilots unfamiliar with the area as such clutter can be a source of confusion or disruption when a number of aircraft are operating in one region.
