Warren Gatland says the autumn internationals are an important stepping stone towards the World Cup in 2015.
Gatland said: "We have an important campaign ahead as we look to test ourselves against some of the best sides in the world but also add strength in depth to our squad as we look to the future."
"We face a huge game against South Africa first up and they will be coming to us after an impressive Rugby Championship campaign."
"Recent matches between us have been very close and physical and that will be a great test for us to kick-off."
"All four matches will be a stern test but we are looking forward to the challenge and looking forward to seeing what we can do on this stage."
"The Rugby World Cup is less than two years away, so we are looking to build as much depth in our squad as possible and to give vital international experience to our players."
