Do I need to fit a new purple cartridge?

Moved from a gravity shower to a combi bolier. Since moving to the new boiler the shower continues to run/drip after use. It eventually stops but it needs a bit of encouragement by running the hot tap in the basin sink in the shower room. It's a Mira Excel TB - low pressure cartridge (yellow) that is currently fitted. Would fitting a purple cartridge and setting it to high pressure solve my problem?

Yes i would fit a new cartridge set to high pressure as it seams like your old one is damaged / faulty.
