National Monuments and War Graves senior advisor Jane Mulryan said, though they were responsible for the maintenance and care of memorials erected by the New Zealand government, the Shannon memorial wasn't one of them.
She confirmed that Mr Wood's surname was correctly spelt in their records and suggested Mr Shearman approach Horowhenua District Council or the Returned Services' Association to find out who was responsible for the Shannon memorial.
Horowhenua district Council confirmed the Shannon war memorial was not their area of business and to contact Veterans' Affairs.
Veterans' Affairs had not responded to Horowhenua Chronicle's email by print time, however Mr Shearman said he is determined to see his great uncle's name corrected.
