"I haven't seen the video yet but from my point of view - it was all bunched up going into turn four and so I bumped it down the outside - it worked because I braked on the racing line so I had more grip and went right around the outside of everyone," he told herald.co.nz.

Armstrong, who was given a scholarship at the prestigious Ferrari Driving Academy, has shown off plenty of his undoubted talent in this series so far - winning races at both Ruapuna and Hampton Downs. He was involved in an incident on the Sunday at Ruapuna, which proved costly but still remained in the championship fight until yesterday.
"I am always honest - I say I made a mistake - but that is one of those times when someone else was in the wrong," a frustrated Armstrong said.
