I don't intend to traverse Mr Peter's statements about the free trade deal, other than to say it is an important issue that should be up for debate.
You do, however, have to question how he has broached the topic.
His statements can be interpreted as divisive and he favours scaremongering over reasoned discussion. This is why he has been put on notice.
Dame Susan was moderate in her response.
She initially declined to comment on his speech but, as pressure mounted, she indicated that she would be forced to get involved if Mr Peters continued his "tirade" against the Chinese community.
She said it was "a broader human rights issue" if Mr Peters continued "to stigmatise one population" to win votes.
Mr Peters is right to focus on issues arising from the free trade deal, but any flaws in the agreement are not the fault of the Chinese community living in New Zealand.
The New Zealand Government must accept this responsibility and that is where he should direct his criticism.
