An Air New Zealand flight attendant has been sacked after mistakenly sending a "highly derogatory and offensive" email about an Air New Zealand manager to the man himself.

Grant Fife, who worked for the airline for 21 years, is fighting for reinstatement.

The trouble arose last September after Air NZ performance and development manager Phil Callahan sent an email to flight attendant Dale Kiely about an insurance claim. A copy was also sent to Mr Fife.
