Tonga's Prime Minister 'Akilisi Pohiva is back in the office this week after returning from medical treatment in New Zealand.
Mr Pohiva returned to Tonga on Saturday after a second stage of his treatment, originally set for last week, was rescheduled.
A spokesman for the Prime Minister said Mr Pohiva is continuing to take medication but will return to New Zealand in June for a reassessment.
On 8 May the Prime Minister underwent the first stage of his treatment at Auckland's Mercy Hospital for a liver complication.
