Hmm... looks like gale-force NW'ers that day along with rain.
This
Wunderground WS about 7 km SE of Wanganui might be of some use. It's a little higher than the town and mean-winds may be 1-minute averages?
Theres's also a NIWA monitored EWS at Wanganui's Spriggens Park and although winds there didn't seem quite as high as the airport, gusts were near 80 km/h late morn, early arvo.
Below are hourly 10-minute average winds from MetService's Wanganui Aero site c/o NIWA/CliFlo (no gusts sorry)...
