The microlight which crashed near Pukekohe yesterday, injuring two men, was performing a routine manoeuvre.
The Civil Aviation Authority is unlikely to investigate the crash, which left two men in hospital.
Two men in their 60s were taken to Middlemore Hospital in a serious condition after crash-landing in a private airstrip off Runciman Rd at 2.11pm on Saturday.
Their conditions were reported to be stable today.
The CAA is waiting on a report from the microlight's pilot instead of conducting a ground investigation.
