Key should have given permission to release the recording almost immediately, quashing the issue, says Edwards. Instead, the first response was a "nuclear" press release from Joyce. He says the release sent Key down the "wrong track" and they had continued on that course since. Now, Key faces another week of Teagate coverage as freelance cameraman Bradley Ambrose goes to court to clear his name.
Edwards says the absence from the campaign trail of chief press secretary Kevin Taylor has deprived Key of an adviser who would avoid "radical" steps.
Key's inner circle of advisers is headed by Joyce, who led National's campaign in 2005 and 2008. The National Party's campaign manager is Jo de Joux.
She had a strong role in the Mana byelection campaign last year, which gave rising National star Hekia Parata the chance to show her potential.
The links between the party machine and the Prime Minister's inner sanctum are close. De Joux's husband Phil is Key's deputy chief of staff. His immediate boss is chief of staff Eagleson, who caused a stir last year when it emerged he was partying in Las Vegas with lobbyists. He has been a strategically important manager for Key.
Another central figure has been less directly involved this time - Kevin Taylor has remained in the Beehive.
His nickname among some senior Caucus members - "Captain Panic Pants" - reflects Taylor's terse nature.
Another factor in the way things have played out is that Murray McCully, one of the smartest in the party, has been overseas at Apec.
