WELLINGTON, New Zealand — New Zealand soccer coach Anthony Hudson has resigned a week after his team’s loss to Peru in an intercontinental World Cup qualifying playoff. England-born Hudson, 36, announced his decision in a statement released Thursday by Football New Zealand which said a search for his replacement would begin immediately. New Zealand won the Oceania World Cup qualifying series but lost to Peru in the intercontinental playoff, drawing 0-0 in the first leg in Wellington and losing the return leg 2-0 in Lima.
