The travels of emperor penguin Happy Feet can be followed online thanks to the Havelock North-based company Sirtrack, which fitted him with a tracking device.
Sirtrack, which has 25 years of experience in wildlife tracking, designed and built the satellite transmitter, and created a website so people can watch the penquin's travels to Antarctica.
Happy Feet stole hearts after being washed up on the Kapiti Coast in June.
He has spent two months recuperating at Wellington Zoo, and departed for home on the Niwa vessel, Tangaroa, earlier this week.
In about three days he will be dropped in the ocean to fend for himself, while the ship continues on its research mission to the Campbell Islands.
