The data tables sort of go into that, on page 15 where it talks about exposure mode. However, the data aren't broken down by year; it merely looks at all diagnoses from 2004-2006.
Interestingly, male/male sex without IV drug use and "undetermined" are the two lead causes, at 37% -- in fact, undetermined is highest. (Though, note that "heterosexual sex with partners with unknown risk and HIV status" is rather disingenously included under "undetermined". If that were combined with the "heterosexual sex" category, that would be a whopping 33% of cases. Dammit, people, use condoms!)
I can understand why they didn't put that in the report, though; getting people to tell the truth about their sexual orientation is hard due to stigmatisation (boo, hiss), and people are probably self-reporting about how they got infected.
