Members of Parliament

The motion was filed on Tuesday by 10 MPs.

An MP who does not wish to be named, told Matangi Tonga that eight people's representatives and two noble representatives had submitted the motion.

No further details have emerged.

There are 26 seats in Tonga's Legislative Assembly comprising nine noble's representatives and 17 people's representatives have 17.

A by-election is coming up, triggered by the death of the previous MP.

In the past two years, four MPs have died and they all had gone overseas for medical help, funded by taxpayer money.

This means that three by-elections have already taken place in Tonga, with a fourth one due on July 13.

RNZ Pacific's Tonga correspondent, Kalafi Moala, said: " there is a real concerrn in Tonga for healthy members of parliament, to allow them to spend more of their time in parliament and not in hospital."

Mr Brown says with the support from New Zealand, they've managed to receive sufficient Pfizer vaccine to provide full coverage for the population.

All residents in the Cook Islands over the age of 16 years are eligible for vaccination.

New Zealand support includes technical advice, vaccine logistics planning and support and vaccinator workforce training. It also includes the supply of consumables such as syringes and the transportation of the vaccine.
