New Years Honours: where is the consistency?

I'm confused. The New Years honours list has just been announced, and it appears some odd choices have been made. Two recipients of high honour are Dame Alison Paterson and Sir Robert (Bob) Parker, both of whom are well-known in governance circles. When one looks at the credentials of Dame Alison, it's easy to see why she was nominated and supported. However with Sir Bob, the picture is less clear.

• Dame Alison has served as a company director and board chair for four decades. She was a pioneer in terms of female directors, and most of the companies she has been associated with have performed well. Dame Alison is widely respected.
• Sir Bob is a well-known media personality and former mayor of Christchurch. While he was the 'face' of the Christchurch earthquake response, he has also been associated with several failures of governance, including a CEO pay debacle and the Council losing the right to issue building permits. His knighthood has polarised opinion.

On the surface, one recipient has served consistently, with distinction, over a long period. In contrast, the other has been a mediocre contributor, save a high-profile media role following a natural disaster. The credibility of the honours system, particularly the bestowing of knighthoods, is dependent on the consistent application of demanding criteria, lest it be reduced to 'gongs for mates'. 

Have I missed something, or are there a few inconsistencies in play this time around?
