The RSA has condemned the desecration of Anzac war graves in London as a "wanton act of vandalism".
"Such an act is appalling and can never be justified in any way," said New Zealand Returned and Services Association chief David Moger.
"It is completely disrespectful to all those who gave their lives in service."
It emerged yesterday that the graves, dedicated to New Zealand soldiers who died in World War I, had been defaced with spray paint.
The vandalism was discovered at Harefield churchyard in Hillingdon, west London.
