Dr Valentine, 86, said Mr Jennings bought a property neighbouring his beachside mansion, knocked the house down and grew a garden, which included the trees which block his view.
Mr Jennings owns the Oakura property, which is across the road from Dr Valentine's home, but does not spend much time there. The retired doctor said the trees were encroaching on council property but despite his many complaints, the New Plymouth City council had not done anything about it.
"I'm annoyed more about the council than about Jennings because he's pretty remote from the whole thing.
"But the city council should have the guts to do something."
A spokesman for the New Plymouth District Council said the council was unable to comment last night.
