"I took their comments literally and began imitating Mike's centre-right, commonsense, daily editorial rants for our morning show."
What began as a fun gimmick for the rock music station has turned into appointment listening, and Wells says they have Hosking to thank.
"Like Seven Sharp, we noticed an immediate rise in the show's popularity - a media phenomenon that has been coined 'the Hosking factor'. Hosking is ratings Ritalin."
Wells' co-star Matt Heath says Hosking shouldn't take offence.
"He has better hair, clothes and ratings than us.
"He doesn't need to waste his time worrying about bottom-feeders like us."
Newstalk ZB boss Dallas Gurney confirms Hosking is taking the segments in the spirit they're intended.
"Mike is amused and thinks they're really funny. He can have a laugh at himself."
Hosking is now off air for a two-week holiday. Wells reckons Gurney has asked him to "fill in for Mike by impersonating Mike".
Gurney laughed: "No, there's only one Mike Hosking."
