Air New Zealand is accusing Labour of trashing its "beloved" koru symbol in advertising opposing Government plans to sell shares in state assets, including the airline.
Chief executive Rob Fyfe has written to Labour leader Phil Goff complaining that the election advertisement, which is screening on television and the back of buses, "denigrates and debases a symbol that we cherish and one I believe all New Zealanders cherish."
He said the use of the koru to provoke political controversy was in conflict with its core meaning.
But Mr Goff told the Weekend Herald that far from denigrating the emblem, "we cherish the airline that the [former] Labour Government bought back from the private sector when they bankrupted it".
The advertisement starts by featuring the symbol, which represents new life in the form of an unfolding fern and appears on the tails of all Air New Zealand aircraft, as an approximation of the letter "e" in the word "assets".
