Photos and videos of a lingering white plume, shaped like a tadpole, against a purple pre-dawn sky, posted to social media by Bay of Plenty residents have captured the result of a Rocket Launch from Mahia Peninsula on Wednesday morning.

Rocket Lab said it successfully launched "Electron" as part of its Owl New World mission, about 5.33am on Wednesday.

The images have spurred discussions on the Tauranga, Papamoa and Mount community page on Facebook, with one resident describing it as a "sky whale", and another posting "a sperm lost in space".

RNZ has also received news tips from people who have taken photos of the phenomena, including from a resident south of Hamilton.
