The man shot and tasered by police in Porirua early this morning is in a stable condition at Wellington Hospital.
The two women who were injured in the incident are also stable, a hospital spokesman said.
Police were still carrying out scene investigations at the house in Penguin Grove, Waitangirua, and a cordon was expected to remain in place for some time, spokesman Nick Bohm said.
Police had not yet laid any charges against the man, and Mr Bohm said that would be considered tomorrow.
The 47-year-old man was shot and tasered at the same time, when police found him allegedly assaulting a 39-year-old woman with a knife and hammer.
