New Zealand reached their second World Cup final in a row because of their experience and composure, according to head coach Steve Hansen.
The defending champions dug deep to come from behind at half-time and beat 2007 champions South Africa 20-18 at a sodden Twickenham on Saturday.
Hansen told BBC Sport: "We've had moments where we had to keep that self-belief. Then in those moments it's just about the process. It becomes the norm. It's a learned skill and self-belief is massive.
"We just needed to come out for the second half and start taking the game to them rather than waiting for them to take it to us. We talked about it at half-time. We talked about keeping composure and talked about winning the first 10 minutes."
New Zealand will return to Twickenham to face either Argentina or Australia in the final next Saturday.
