The Premium Visa is valid for a period of one year and is renewable.

A premium visa is required for those who intend to stay in Mauritius for a period exceeding 180 days in a calendar year. Those staying for less than180 days, a tourist visa is granted on arrival to Mauritius.

FWIW: On the EDB. site:

A foreign national staying in Mauritius under a Premium Visa may apply for an Occupation Permit if he intends to work or invest in Mauritius or a Residence Permit as a retired non-citizen.

The word may聽 implies a lot AFAIK聽 wrt the civil servants at EDB !聽

This says聽 it all:

to any non-citizen who intends to stay in Mauritius for a maximum period of one year as a tourist, retiree or a professional willing to come with his/her family and carry out his business or work remotely from Mauritius.

Tourist聽 more than the 6 months Tourist visa
Retiree who wants to spend more that 6 months on the island聽 for whatever reasons
Professional : guess it is appropriate for the digital nomad who hops around from location to location < 6 months and is cornered by CV-19 to move around
