Hoiho has been crowned the Bird of the Year.
Its the first win for seabirds in the competition's 14 year history.
It was neck and neck with the kākāpō for much of the two week competition - only edging ahead in the final few days.
"It was so close between these two amazing endangered birds, it was impossible to predict a winner for most of the competition," said Forest & Bird spokesperson Megan Hubscher.
The hoiho is the world's rarest penguin, with only 225 pairs remaining on mainland New Zealand in 2018/19.
