It's probably more accurate to say "human ratable". They're planning on designing the rocket with human rating in mind, so that if they want to do it in the future, it'll be easier.
But NASA doesn't human rate a rocket - they human rate the entire system as a whole, so it doesn't really make sense to say "human rate Neutron".
I wonder how that's supposed to work with their unique captive fairing design. Feels like they'd have to design crew flight specific boosters which don't have the fairings.
Rocket Lab mentions “human spaceflight” on the Neutron page, that’s the only mention I’ve seen of it. I haven’t seen any plans for a spacecraft for carrying humans or how they might handle re-entry.
