That is sort of like asking, "If the weather is reported to be below my approach ban limits prior to passing my approach ban decision point, can I land?"
CAT 3 is not just about your qualifications and the capabilities of your aircraft. It is also predicated on airport equipment capabilities, such as lighting, ILS signal integrity, ground movement restrictions etc. Many runways / airports are certified for CAT 2, but not for CAT 3. So, unless you confirm that CAT 3 is approved and that the airport is operating to CAT 3 specifications, you cannot land in CAT 2 operations using CAT 3 minima. I do not have access to your local regulations so I cannot provide a reference. I recommend that you ask your Civil Aviation Authority for that information.
