"I've been telling you for years... about this person's incompetence and the incompetence of a number of National Party people to actually understand business or to represent our country properly."
"I've told the public for decades what's wrong and here you've got a screaming example of it," Peters said in comments broadcast by 1 News.
Radio New Zealand reported today that sources had told it Shipley's role on the executive board of the New Zealand China Council had already been discussed among senior Cabinet ministers following yesterday's High Court ruling.
Prime Minister Jacinda Ardern was also asked today what the Government would do about Shipley's position on high-profile boards.
"It would very much depend on which boards you might referencing," she told reporters.
Ardern declined to comment further while an appeal might be under consideration.
Peters' attack on Shipley was his second in as many weeks.
He made similar comments last week after an article appeared in China's People's Daily under her byline which complimented China on its reforms and the Belt and Road Initiative.
When asked by reporters to comment on the article, Peters questioned her credentials to chair the China Construction Bank NZ and he referenced the BNZ crisis of the early 1990s when she and he were both in the National Party.
"It is actually extraordinary that some who has so little knowledge of banking, for example, should be in the second biggest bank in China," Peters said at Parliament.
Shipley later denied she was the author of the opinion piece but Peters did not backtrack on his comments.
The animosity between the two goes back to 1998, when Shipley sacked him as treasurer and deputy prime minister in a coalition government.
