As you can see from the log above, time machine had attempted to make a full backup. In the end, I decided to let it run and I'm now left with backups dating back to JUN 2012.
However, this morning I discovered another issue and I think this might explain why it decided to make a full backup.
I scrolled back through my recent backups in time machine and as I went backups from before the switch to the new iMac I found they were all empty. Looking at the time macine volume directly I can still see the files however, I have no permission to read them. All files are owned by "temp" which is a temporary user I created for restoring the backups. I did this because when I first setup the new iMac I used my real account details and then found that I couldn't restore the backups as it was complaining that the user existed.
So I think the real problem is that I setup the temp user as the first and only account when I reinstalled OS X and this meant temp got the UID 501; therefore, all old backups which were created under my real account which also had UID 501 were linked to the temp user. When I created my real account account I was assigned ID 502. Hence the need to create a new full backup.
Not sure what to do now...

Looks like I should have read this before I started:
