The film uses time-lapse photography, he said, which he hoped would bring into sharp focus the loss to light pollution of night-sky views around the world.
"I spend a lot of time photographing the night sky and have seen many of the negative effects that light pollution can have. So I thought one of the best ways to educate people about light pollution would be to show them the difference between a light-polluted city sky and a dark sky with little or no light pollution," he said.
"The footage was shot around the Wellington and Wairarapa region on the North Island of New Zealand. We are very lucky here as the light pollution around Wellington itself is nowhere near as bad as it is in larger cities such as New York, London or Sydney."
He said the capital was surrounded by hills "so a lot of the light pollution is contained within, and you can travel just 20 minutes out of the city centre to find skies dark enough to view the Milky Way".
"I also travelled to locations with varying degrees of dark skies. From locations with moderate light pollution to the darkest of skies miles from anywhere in the Wairarapa - it was an interesting exercise to see what is visible in the night sky as you go from place to place."
He earlier said Wairarapa had a dark sky more than equal to the internationally gold-rated Aoraki Mackenzie Dark Sky Reserve - the first and only such reserve in New Zealand - and he would back any call to make Wairarapa a dark sky reserve.
Gee said he had spoken to numerous people around the world who had viewed his work and "was truly shocked when some of them said to me they have never seen the Milky Way with their own eyes before".
He had since discovered that more than a fifth of the world's population, two-thirds of the US population and half of the EU population had lost naked eye visibility of the Milky Way.
Gee branded the night sky blindness "a real shame" and urged people to stargaze beyond city boundaries during International Dark Sky Week.
"It can be a truly humbling experience, especially if you haven't done it before. It's certainly a release for me from everyday life. After all, life without dark skies - you don't know what you are missing."
International Dark Sky Week runs until April 26 and aimed to inspire people to celebrate the beauty of the night sky and raise awareness of the effects of light pollution.
