Angry with his neighbour and extremely intoxicated, Stephen Robert Walker got his axe and smashed the woman's letterbox with it.
Walker then headed down Carterton's High St, swinging the axe at another letterbox and wooden fence as he yelled "come and have a go".
The Carterton man, 55, pleaded guilty to possession of an offensive weapon, an axe, and intentional damage when he appeared before Judge Geoffrey Ellis in the Masterton District Court recently.
Police prosecutor sergeant Garry Wilson told the court the incidents happened early in the evening of October 10.
"He used the axe to smash the letterboxes ... he was extremely intoxicated," Mr Wilson said.
