Military-industrial outfit Lockheed Martin - recently subject to a jibe from Michael Stiassny - is not listed, indicating its stake would have watered down by the Series E round.
Funding will support continued Electron vehicle production expansion, new launch sites in the US and UK and three new major research and development programs.
A spokesman for ACC refused to say how much the Crown agency had invested in Rocket Lab, citing "commercial reasons," but described it as a "meaningful amount."
The funding round follows Rocket Lab's first successful launch last week.
Tindall says, "The team at Rocket Lab has been inspirational and have now proved themselves to be the only operational private small launch provider globally. Their contribution to the NZ tech sector will continue to increase as they ramp up the launch frequency."
On Monday, founder and CEO Peter Beck told the Herald that Rocket Lab will be cash-flow positive by the end of this year.
Beck says 2600 satellite launches are planned over the next four years - representing more than US$3b in potential business.
