The shortage has been linked to the recent severe drought which destroyed many kava plantations.
All kava market areas in the sub-residential areas have been witnessing people queuing up to get their share whenever an interisland vessel arrives in the capital from the outer islands in the hope of getting their shares.
Kava production is struggling to cope with increased demand around Vanuatu's islands.
More farmers in outer islands are selling directly to local bars rather than shipping to Port Vila on Efate where there is no kava production.
