''Tom has added experience that allows us to strengthen the higher middle order, with Ross (Taylor) at No 4 and Neil Broom at five."
The extra buzz of facing Australia remains intact for New Zealand's cricket team, according to Williamson.
With the amount of cricket played in the modern game around the world, it would be easy for Australian contests to be seen as just another assignment.
Not so, says champion batsman Williamson.
''In any sport they are our neighbours and there's always that competition when you play them.
''You are wanting to be at your best and you know when you come up against Australia in any sport, they'll (provide) stiff competition. At the moment they are setting the benchmark (in cricket).
''Any time you have the opportunity to play the best, you want to show up and put out a performance than can beat the best."
