I will present our recent calculation of previously unavailable Nf-contributions at NNLO to the production of three massive vector bosons. For the first time at two loops, we enable their direct numerical integration by tackling infrared, ultraviolet and threshold singularities simultaneously using local subtractions. I will discuss our numerical method and describe the next steps towards calculating the full NNLO contribution.
