They pay a visit to the Southland Times, where it all began, and find it but a shadow of its former self, though still capable of inspiring memories of wonderful newspaper characters, hilarious moments and stupendous drinking sessions.
Naturally they visit many pubs, finding them generally changed for the worse, but thanks to McBride's ebullient personality still capable of providing interesting chats with locals, plus a goodly supply of beers.
They also drop into places as different as Riverton, Stewart Island - no oysters! - Tuatapere, Nightcaps, Naseby - for curling - the ruins of Seacliff Mental Hospital, Palmerston - mutton pies - and Cromwell, each of which spark memories, good and bad, personal and historical.
Finally, after six days, they're back at Queenstown Airport, "wiser perhaps", says Hogg, "certainly dustier". "It seems like we've been away a lifetime."
Since then McBride and his partner, Trish, have ticked a couple of things off their bucket list and, at the time of writing, he continues to fire off provocative tweets. Hogg, meanwhile, had another spectacular session with his old friend, Sam Hunt, and ended up requiring an ambulance. Afterwards, his 16-year-old daughter took him aside and said, "Your party days are over, Daddy. You're an old man."
Indeed. And we've all got despondent about the news business too. Hey ho. Sic transit gloria mundi. But well worth remembering, for all that.
