On the AM show this week Simon Bridges said he supported the teaching of Te Reo but would not make it compulsory. I would say that Labour won't be rushing to make it a compulsory subject either.
For the last many weeks columnist Joel Maxwell has been extolling the virtues of learning Te Reo describing his personal journey towards fluency in Te Reo. As the weeks have gone by the number of negative comments & down votes about Joel and Te Reo seem to have grown and grown. Each week a few people will comment in support of the column but the vast majority are in opposition.
While one could say that Stuff commenters are mostly conservative, white, and old, the sheer number of negative comments would make any politician wanting to make Te Reo compulsory in schools a little nervous.
Here is a screenshot of 3 comments and down votes from his 3 Sept. 2018 column. (Actually up votes on the comments made)
