Petrie moved to Canada in 2001 , becoming a newsreader for the CTV News Channel and a substitute newsreader on the CTV morning programme '' Canada AM '' . During her time in Canada , she reported on the September 11 attacks for 3 News . In late 2003 , Petrie returned to New Zealand and joined TVNZ , initially as a fill-in presenter across all '' One News '' bulletins . She was on air when the Boxing Day tsunami took place , as well as during the 2005 London bombings ; for this , as well as her earlier reports on the September 11 attacks , she was jokingly dubbed a ' disaster magnet ' by former boss Bill Ralston . In 2006 , Petrie became co-anchor of the 6 pm edition of '' One News '' alongside Simon Dallow ; she replaced Judy Bailey as the primary female anchor , who had held the position for 18 years
