'Population size' was estimated based on photo-identification mark/recapture analysis.

- Previous underwater recordings in New Zealand have identified low-frequency sounds attributed to blue whales, resembling their songs from other regions.
- During a recent Southern Ocean Research Partnership voyage, these sounds were recorded while traveling from New Zealand to Antarctica and back.
- The study shows that blue whale songs in the area have changed slowly over the past 50 years, indicating a stable population year-round and a significant range extension to the south.
