The birth of seven new fairy terns has boosted the population of one of New Zealand's rarest birds.
The birds, also called the tara-iti, have "teetered" on the brink of extinction since 1970, the Department of Conservation said.
There are fewer than 40 adult fairy terns and they continue to be critically endangered despite intensive management.
However, the latest breeding season has boosted the population by about 20 per cent.
"Seven chicks is a great season – last year (2018-2019 season) we only had two chicks fledge, so this is a big improvement," biodiversity ranger Ayla Wiles said.
