No. You can't delete a law by making a law, that's obviously a contradiction.
All repeals are acts of Parliament. However, Acts are essentially diffs to the existing body of law. If you read one you'll see they're full of "insert paragraph X after paragraph Y" type language. An act that repealed a law would just be an act that stated such-and-such a paragraph in the law was to be erased.
