An understanding of the language and culture is intended output for most Te Reo courses, not fluency. I'd suggest most meet the objective.
I'm just surprised that in 2018 a business leader doing an intro in Te Reo is still an issue. Its pretty standard at many events I attend. Part of being a NZ'er, connected to Aotearoa.
p.s. wonder if Ngai Tahu will go A2 at Eyrewell, useful volume of milk for someone. Or longer term even take a position in SML itself ?
