"Fans back home are passionate about and love rugby, but it is definitely a step up over here. Even a couple of hours after the game once we've changed, there is always a big crowd around for pictures and autographs. In New Zealand, we certainly don't have that. There's more passion for rugby here in Cape Town - South Africans are definitely more rugby crazy."
Treeby, who has played a nice 69 times in the National Provincial Championship with Wellington, argues that the South African Super Rugby sides are evolving to play a more expansive style, but are still lagging behind with skill development.
"Back when I started playing Super Rugby, we knew what to expect from a South African team. They mauled, used their big forwards and kicked a lot. They were really good at it. But with the new rules, teams have to score more points and play more attacking rugby. There has been a definite shift to a more expansive style of play.
"In New Zealand from a young age skill work is a huge part of training. Coming here, I found it interesting that many of my teammates, especially the forwards, didn't do that much skill work growing up. However, there's a much greater emphasis on technical skills now. We're focusing on offloads and doing more skill work at the Stormers."
One of the biggest differences, says Treeby, is line speed, where the Hurricanes and Crusaders lead the way in putting defensive pressure onto their opposition.
However, he thinks that South Africa can catch up, and that there's little separating the two nations.
There's a big perception that there's a massive gap between New Zealand and South African rugby currently, but I can tell you that it's definitely not true."
