Engineering issues have forced an Air New Zealand plane back to the ground in Christchurch on Sunday evening.
A flight tracking website showed the plane - bound for Hamilton - made it as far north as Blenheim before performing a u-turn.
It landed back in Christchurch before 8pm.
The flight returned due to "engineering", an Air New Zealand spokesperson said.
Customers would be booked on the next available flight to Hamilton.
