"Brad brings a great deal of professionalism to any team he plays for. His work ethic, experience and leadership will add a great deal to our team and have a very positive influence on the younger players" commented Joseph.
"Brad is a very competitive athlete and from what I saw in Japan recently he is still playing rugby at an International standard".
"We talk a lot about the culture at the Highlanders and Brad is a perfect fit, both on and off the field" added Joseph.
Joseph had been in Japan recently, where Thorn was playing, and said he was still playing to a high level.
Thorn, who will be 38 in February, last played in New Zealand at the World Cup last year.
His presence at the Highlanders will be a huge boost as the side looks to build to a strong 2012 campaign.
