White humpback whales are extremely rare in the world. Migaloo was the first one to be seen back in 1991 and since then, he has usually been spotted off the coast of Australia during the annual migration from Antarctica to the tropical waters.
They spotted the white humpback along with a typical black humpback while conducting a whale survey in Cook Strait.

In a New Zealand's Department of Conservation news release, the boat captain is quoted as saying, "I thought, wow that whale is white, that is amazing!"
The survey team says that the whale has same distinctive features as Migaloo.
According to the New Zealand's Department of Conservation, "a skin sample for DNA analysis was taken from the white whale ... with a biopsy dart and will be compared with Migaloo's DNA to confirm whether it is definitely the same whale. The analysis will also identify whether the whale is albino or whether its whiteness is due to color variation."
The department notes that yellow spots seen on the whale's body are marine algae which will disappear as the white whale spends more time in warmer waters.
A rare albino buffalo (C) grazes next to its mother (L) in Hellsgate national park in Naivasha after it was discovered by wardens. Kenya Wildlife Service said that this is the first ever albino buffalo found in the country's park as albinism in wild animals is very rare. Scientists say that though the animal is in good health, it's an easy target as it stands out due to lack of colour pigmentation. (Photo via AFP/Getty Images)

The herd of about 30 buffalo boasts three white buffalo that are a big attraction for the museum not only because of the rarity of an albino buffalo but also because of the sacredness that some Native Americans place on a white buffalo.
