Despite the footage being owned by Three, the Herald understands Keane has accused the network of plagiarism, venting her anger on her personal Facebook page.
Campbell Live's earthquake coverage included setting up a 'Caravan of Complaint' for survivors to vent about their experiences rebuilding their lives after the natural disaster.
Keane later took to Twitter to complain that Three had called its earthquake coverage "depressing" and cited it as a reason for Campbell Live's axing.
She also asked why The Project didn't send its own reporters or presenters to Christchurch to report on the anniversary.
Three declined to comment on the issue. Keane declined the opportunity to comment further.
Viewers also picked up on the segment, with one calling Three "hypocrites" for using the footage.
The Project is the latest show to be placed in the slot vacated by Campbell Live after Come Dine With Me and then Story.
Fronted by Jesse Mulligan, Kanoa Lloyd and Josh Thomson, The Project is a New Zealand take on a popular Australian series that aims to take a lively, energetic and humourous look at the day's news.
Initial reviews of the programme were positive, although it's understood ratings have declined since the series debuted on Monday night.
