Narrative:
This event occurred while flying the ILS 6 / circle to land 1 approach at teb. It was nighttime and the weather was VMC; winds were 320/18g33 with light to moderate turbulence reported on approach. Prior to circling; tower reported the traffic we were following and instructed us to square our turns to final (to increase our spacing). I initiated our circle; turning to the right approximately 60 degrees (more than would normally be required for the circle). As we descended and began to turn back to final; we received an obstacle alert from the aircraft warning system. I began to raise the nose and the alert ceased after just a few seconds. I completed the turn to final and we landed.suggestions: more adequate spacing between us and the preceding aircraft would have negated the tower's instructions for us to alter our planned circling path. I believe by lengthening the circling path and the amount of turn required; the expected geometry changed. This added to the workload; making glide path management more difficult. Or we could have continued to fly the planned circling path and executed a go-around if inadequate spacing developed.
