Rocket Lab has completed civic works at Onenui Station on Mahia Peninsula, and is now in a commissioning phase. When completed it will be the launch site of its Electron vehicle, with the first test flight scheduled for later this year, followed by flights each month.
Rocket Lab CEO Peter Beck said the Government's commitment to seeing New Zealand join the global space arena was exciting news for the country.
"As with any industry, there is a need for a regulatory framework," he said. "Rocket Lab is committed to international best practice on using space responsibly, peacefully and sustainably."
He said the space economy generated more than $330 billion annually.
"We look forward to seeing New Zealand-based players enter the industry, and what this will mean for our economy and country's reputation as being at the forefront of global advancements in technology and engineering."
The proposed new law was required to both implement the TSA and the Registration Convention, and ensure rocket and high-altitude vehicle launches from New Zealand, and the satellites they put into orbit, were done safely and were not contrary to national interest.
New Zealand also reserved the ability to prevent a launch in the country which was contrary to its law or policies.
Mr McCully said: "The development of a New Zealand space industry is another exciting opportunity for our country. These agreements will ensure New Zealand is well set up to be a responsible and trusted participant in the global space industry."
The TSA has been designated as a major bilateral treaty of particular significance.
