Had a car accident just last night (10:35pm)
I'm travelling south along Domion road in Auckland. I realize I've missed a turn/got lost, so I start indicating to the left as i wanted to pull over to figure out where i need to go. I indicated longer than the required 3 seconds b4 making the lane change.
I Checked rear view and looked over my shoulder twice and thought it was clear to pull into the green marked bus lane then stop after the yellow lines. As I start turning into the bus lane, a car (not sure if he was over or under the speed limit) manages to overtake me and in the process we make contact resulting in major panel damage of both our cars.
From my understanding, overtaking someone from the left is not allowed - He acknowledges that he sped up as I was indicating.
But given the circumstances that i was moving into his lane i think i could possibly at fault? - although i did everything in my power to make sure the lane change was safe.
I have 2 witnesses and he has none. He doesn't have insurance, I have 3rd party, $800 excess

Both drivers are fully licensed.
Who is at fault here? any help appreciated thanks.
