This is a different company (Rocket Labs) so they wouldn't get to reuse SpaceX's capture methods. This method appears like it would allow them to use commodity helicopters instead of having to develop and build their own drone ship tech, which has the additional hassle of having to maintain a boat and have a dock they can use to haul the rocket. I'm guessing this is for their "Small Launch" offering so the heli option makes sense at that weight.
