The first foreign aid plane has arrived in Tonga, carrying much-needed water and supplies for the Pacific nation.
New Zealand said its military plane landed at Tonga’s main airport after workers cleared ash from the runway.
Other planes and ships sent by New Zealand and Australia are on the way.
Saturday’s eruption of an undersea volcano and tsunami wave saw volcanic ash blanketing the islands, posing a serious health risk. The ash and sea water have contaminated water supplies.
At least three people have died and communications have been crippled, and Tonga has only just begun to re-establish global contact after five days cut off from the rest of the world.
A thick layer of ash had covered the airport runway in the capital Nuku’alofa, preventing planes from landing.
For days rescue teams and hundreds of volunteers desperately worked to clear the tarmac using wheelbarrows and shovels, in what New Zealand’s commander of joint forces Rear Admiral Jim Gilmour called a “mammoth effort”.
He told reporters on Thursday that their C-130 Hercules plane touched down in Tonga just after 16:00 local time (03:00 GMT). It was loaded with water containers, temporary shelter kits, electricity generators, hygiene and family kits and communications equipment.
Australia said the first of its two Boeing C-17 Globemaster planes arriving on Thursday that were carrying supplies also had a “sweeping” device on board to help keep the runway clear.
Both Australian and New Zealand authorities have confirmed that the drops will be contactless, to prevent the risk of Covid spreading to the island which has seen just one case of the virus so far in the pandemic.
“The aircraft is expected to be on the ground for up to 90 minutes before returning to New Zealand,” said New Zealand’s Defence Minister Peeni Henare.
Rear Adm Gilmour said no-contact Covid protocols were “being adhere to rigorously”, adding that relief procedures would include making sure the airplane crew would have no contact with anyone on the ground, and that everyone would be wearing personal protective equipment (PPE).
“We are very respectful that the last thing that Tonga would need now is a Covid outbreak on top of this disaster,” he added.
Australia has also said no personnel would disembark from their planes.
A New Zealand naval ship is also due to arrive in Tonga on Thursday, ahead of other supply ships.
Authorities said HMNZS Wellington’s first task was to scope out “shipping channels and wharf approaches to Tonga’s port to ensure vehicles can go alongside [it].”
Mr Henare earlier told the BBC the supply ships would bring more than 250,000 litres of fresh water and desalination equipment, used to separate salt from water.
“The most pressing matter that’s come through from the Tongan government is the need for fresh water,” he said.
