Rocket Lab has scrubbed its launch attempt today, blaming unfavourable weather and orbital traffic - the International Space Station.
It says it will try again tomorrow.
The scrub was called shortly after the window opened at 2.30 pm.
''A combination of poor weather closing in and conjunction with the International Space Station left a narrow six-minute window for a launch attempt,'' a spokeswoman said.
A new attempt will be made no earlier than 2.30pm tomorrow. The launch will be livestreamed and can be viewed on nzherald.co.nz.
