Chief Employment Court Judge Graeme Colgan has been criticised by the Court of Appeal for taking 26 months to deliver a judgment.
Judge Colgan apologised to the parties for the delay but the Court of Appeal still described it as wholly unsatisfactory.
It said the delay came close to meeting the test whereby the delay itself could create a question of law, being that the judge could no longer do justice between the parties.
It is not the first time Judge Colgan has been singled out for being especially slow.
Justice Minister Judith Collins last year cited three of his decisions when explaining why she wanted to require chief judges of various courts to set up protocols about reserved decisions and timeliness of delivery.
