The Bath back row man has only managed 62 minutes of international rugby so far in 2011, but the 2003 World Cup winner aims to make up for lost time at his third global tournament.
A replacement in the triumph over Australia in 2003, he started in the 2007 World Cup final against South Africa, but couldn't stop the Springboks from taking the title for the second time.
But 'Mad Dog' believes he is now "on the right path" and is ready to add to his 67 England caps, and three for the Lions, and try to lead England into a third successive World Cup final.
"Everyone has been very confident and I am happy at how it has gone. The target is still playing against Argentina," said Moody.
"The most important thing is that the medics and the physios are happy with me and they are not going to risk me if it is not right. I don't want to go in and knacker the knee again."
Fellow Lion Simon Shaw has now arrived in New Zealand after delaying his departure due to a stomach upset and is expected to train fully this week in the build-up to the Argentina game
