I flew into welly the same day as San (only 5 hours later) and we had a calm landing lol...... apparently Christchurch also had problems that day as I was booked to fly Hokitika -chch but the plane (admittedly they are the small ones) couldn't take off from christchurch to fly to Hokitika, hence they bussed us to Christchurch.
Oh what a wonderful way to get home, left hokitika at 11.45, and finally landed in Wellington at 9.40pm.
