NZ ENCs are encrypted using the IHO S63 Data Protection Scheme. They can be used in IMO compatible ECDIS or in a compatible Electronic Chart System (ECS) which can decrypt IHO S-63 data. Please register to the Service to use ENC data.
It is important to load the latest set of permits when loading base or update data. Failure to load the latest permits corresponding to an update or new base data will deny access to new cells.
