Mr Chompski was a mass simulator to test a new 3D printing technique that Rocket Lab could use for future spacecraft components.
Unfortunately, the 150mm titanium gnome's time in space is limited.
He remains attached to the third section of the rocket, called the Kick Stage, which burns up on re-entry into the Earth's atmosphere.
The launch also raised a large amount of money for the Starship Foundation with Gabe Newell of Valve Software and The Heart of Racing pledging to donate $1 for every view the livestream received.
Gnome Chompski is the name of the garden gnome in games created by Valve Software - creators at the company are fans of the linguist and scientist Noam Chomsky and saw the opportunity to make a play on words for the character.
In the games, there is an achievement involving Gnome Chompski known as "Little Rocket Man" status, where the player has to carry the gnome throughout the game to place on the rocket.
There were a total of 286,092 views across YouTube, Twitter and Twitch and therefore a total of $286,092 raised.
The stream also inspired influencers to fundraise for the cause like Everyday Astronaut's Tim Dodd, who also raised thousands of dollars for the Starship Foundation during the launch.
"We are delighted to have played a role in supporting the Starship Foundation through this launch," Rocket Lab founder and CEO Peter Beck said.
"We're immensely grateful to all the space fans and gamers who tuned in to help us reach a huge total number of views.
"What Gabe and The Heart of Racing Team have achieved with this initiative will make a difference in the lives of so many Kiwi kids and it has been an honour to be part of it."
Starship Foundation CEO Aisha Daju Punga said they were "blown away" by the support both in New Zealand and globally.
"We want to extend our heartfelt gratitude to Rocket Lab for their willingness to get in behind this initiative and our incredibly generous partner, Gabe Newell and The Heart of Racing team.
"We are truly overwhelmed by the result of this inspiring collaboration of hearts and minds for the children of New Zealand."
