In his letter to Fiamē on May 19, 2025, Peters explains the compensation “resolves all issues arising from the sinking of the HMNZS Manawanui between the government of New Zealand and the government of Samoa” and “the government of Samoa will not seek further payment from New Zealand”.
The New Zealand Government announced the $6m/SAT10m compensation on the first anniversary of the sinking of the HMNZS Manawanui on October 6.
Auckland University of Technology law professor Paul Myburgh thought this amount was a “first down payment” to look after impacted villages: “But reading these letters it becomes apparent that they are attempting to ring-fence all of their liability, apart from a reference – a fairly obscure reference – to ongoing reef assessments, whatever that might mean.”
It was difficult to say what an appropriate compensation amount would be, he said.
“I’m not across all the details, but one thing I’ve learnt from comparative collisions and groundings, etc, is that it is very difficult to assess and cap the damages because they tend to be ongoing. In other words, while that wreck is still on the reef it will continue to cause damage, so any sort of legal attempt to cap the damages indefinitely means that somebody along the line is going to be short-changed.”

Senior lecturer and Pacific Security Fellow at Victoria University’s Centre for Strategic Studies, Dr Iati Iati, was surprised that the letters reference Samoa’s Ministry of Foreign Affairs as having set the compensation figure at 10m tala.
“I hadn’t heard of any process for an independent inquiry for how much the costs would be,” he said.
“I was a little taken aback by the figure of 10 million tala only because I’ve seen a study done by Massey University over the Rena, and it was done I think around 2021 and they estimated costs for the Rena – direct costs that is – around $46 million [NZD]. That wasn’t including indirect costs.”
Iati noted the Rena had sunk much further out at sea in comparison to the Manawanui, and the impact would have been different and probably less than what was experienced in Samoa.
“So it’s left me with a lot of questions as to how they determined that 10 million tala figure,” he said.

Peters’ letter to then-Samoa Prime Minister Fiamē Naomi Mata’afa, dated May 19, 2025, refers to “the long- established and respectful bilateral relationship between New Zealand and Samoa, founded upon sovereign equality and governed by a spirit of close friendship, underpinned by the significant Treaty of Friendship”.
“To be honest it leaves me with more questions than answers. This looks like to me just a very diplomatic way to bring this situation to an end without addressing alot of issues that should have been addressed,” Iati said.
“I’m curious as to whether there’s more to this than just New Zealand sending the Manawanui to do some kind of reef surveying. I’d be interested to know if there were any other actors involved and what their reasons were for the Manawanui to be conducting these exercises on the coast of Samoa, especially given that the order for the Manawanui to conduct this exercise was finalised just as it was leaving port so it seems to me like there’s a wider story here that hasn’t been looked at.”
Iati questioned whether other parties should also be liable for some part of the cost of the impact of the Manawanui that was borne by the Samoan people.
With 40 years’ experience as an oil spill response scientist, Paul Irving was in Samoa soon after the Manawanui sank, for Sprep – the Secretariat of the Pacific Environment Programme.
“My role and function was to work with and for the Samoan government as much as possible. I was effectively loaned to them by Sprep to provide, to organise advice, to seek international support and to give them the best advice possible given that they were not the spiller, their country was the victim.”
Irving said the correspondence between Peters and Fiamē was diplomatic, rather than a letter of compensation or insurance usually associated with one country causing another country injury or harm because of the actions of its sovereign citizens.
“I think $6 million – 10 million tala – is a relatively small amount given that the estimate to remove the vessel from the area was around, between $75m and $100m, so I think New Zealand got away with about 10% of the cost of cleaning up.
“The New Zealand Government certainly was not thinking the same way when it required more than $500m to be spent by the owners of the Rena to clean up the reef in the Bay of Plenty.”
