Ui-te-Rangiora and the 'sea foaming like arrowroot'
A Rarotongan tradition tells of the navigator Ui-te-Rangiora (Hui Te Rangiora) sailing far south to a misty, sunless sea of 'arrowroot foam' with rocks growing out of the water, which some read as the first human sight of Antarctic ice around the 7th century.

The account
The reading comes from the 19th-century ethnographer S. Percy Smith, who took the foam for sea ice and the rocks for icebergs. A 2021 paper by Priscilla Wehi and colleagues in the Journal of the Royal Society of New Zealand revived it, and headlines said Māori had reached Antarctica 1,200 years before Europeans. Atholl Anderson, Tipene O'Regan and other Ngāi Tahu scholars replied that the original tradition says nothing about an Antarctic voyage and that Rarotonga was not settled until about the 10th century. Position is notional.
The sceptical view
The Antarctic link is an interpretation layered onto the story, not part of it; the dating also clashes with the settlement of the Cook Islands.
The researched reading
A genuine Polynesian voyaging tradition whose Antarctic meaning is a later reading. Most specialists doubt it records ice, but the question is about interpretation rather than fabrication, and part of it cannot be resolved.
| Explanation | Weight | Why |
|---|---|---|
| A cultural story | 50% | Anderson, O’Regan and colleagues argue the Hui Te Rangiora story is an origin narrative whose Antarctic reading was added by S. Percy Smith in the 19th century; the original Rarotongan text does not mention an ice voyage. |
| Undetermined | 30% | Oral traditions cannot be dated precisely, and no archaeological trace of an early Antarctic voyage could survive; the question may never be settled. |
| A known natural phenomenon | 15% | Polynesian navigators did sail deep into cold southern waters (the Auckland Islands were reached), so a voyage meeting sea ice or icebergs is not physically impossible, even if this story may not record one. |
| Something known, misidentified | 5% | Arrowroot foam and growing rocks could describe other seas, surf or pumice rather than ice. |
| A hoax or fabrication | 0% | There is no evidence anyone fabricated the tradition; the dispute is about interpretation. |
Official position: No official position; the 2021 paper and its published rebuttal in the Journal of the Royal Society of New Zealand disagree.
