Yes, the CGI effects were done by Sony ImageWorks, but
WETA designed the "Look" of Aliens (Kilowog, Tomar Re, Sinestro, Guardians and others), Planet Oa, Green Lantern Suits, GL power battery in the movie Green Lantern.
Many criticized the look of Oa and the suit designs in the movie.
WETA were also involved in the abandoned movie project Justice League:Mortal, they designed the suits for the Heroes in that.
