Two police aircraft have made several search flights over the sea, police spokesman Indira Bhugobaun told AFP.
Police officers with the coastguard service were also helping in the search at sea around the country's main island, as well as around more remote islands, including the Agalega islands, some 1,000 kilometres (600 miles) northwards.
Searches were also ongoing around the sandbank archipelago of St Brandon, some 430 kilometres northeast from the main island, as well as Rodrigues some 560 kilometres east.
Mauritius police said the search has so far found nothing.
France said today it would launch new air, land and sea searches from Reunion, some 225 kilometres southwest of Mauritius in the hope of finding more wreckage from the missing Malaysia Airlines plane.
The re-energised hunt for MH370 clues follows Malaysian Prime Minister Najib Razak's announcement that a two-metre-long wing part discovered on the French island last week was confirmed as from the missing aircraft, the first proof that it met a tragic end 17 months ago.
