Tryphena is a beach settlement on the southern coast of Great Barrier Island in the Hauraki Gulf of New Zealand's Auckland Region.

[4] SeaLink New Zealand operates a 4.5 hour car ferry between Tryphena and Wynyard Quarter.

[5] The area is a habitat for New Zealand kaka, kererū, rails, pateke, blue penguins, dolphins and orcas.

[6] The bay was traditionally the site of a pā (fortified settlement) of Ngāti Rehua Ngati Wai ki Aotea.

[7] The settlement was renamed Tryphena, after a brig of the same name made several visits to Great Barrier Island between 1841 and 1845.

[6] In May 2020, members of Ngāti Rehua Ngati Wai ki Aotea attempted to establish a checkpoint at the Tryphena Wharf, to prevent people from visiting the island during the COVID-19 pandemic in New Zealand.

The results were 84.8% European (Pākehā), 27.3% Māori, 1.5% Pasifika, 4.5% Asian, and 6.1% other, which includes people giving their ethnicity as "New Zealander".
