The retired secondary school teacher also has novelty flags such as a St Patrick's Day one and the Easter bunny. The smiley-face flag is raised when he is happy and to cheer up anyone who needs it.
He flies the tino rangatiratanga flag during Māori Language Week in support of te reo.
Thana came to New Zealand from Thailand in 1956 to attend Otago Boys' High School and
then the University of Otago. Those southern experiences run deep and he supports the Highlanders - both in voice and with his flagpole. When the team loses the tartan-clad warrior is flown at half-mast.
Thana admires Americans' attachment to flags, in particular how they fly the stars and stripes, state, service and college flags at their homes. He says identity is very much part of American culture.
He'd like to see Manawatū adopt a flag, perhaps designed through a competition, and has noticed more flags flying in Palmy. He does lower his flags in strong winds otherwise they would get "beaten to bits".
He's lived at Olive Tree for five years and brought his flagpole with him.
Thana says flags are ways to express identity, feelings, emotions and loyalty.
Thana taught history and French at Palmerston North Boys' High School and joined Awatapu College in 1976 as a foundation teacher.
