Problems with FDSN station service in obspy

[nbalfour]

I have been playing with the station service and queries are broken in obspy, but not in the URL, but they return different things with the URL, but that is not surprising. Anyway, it summary I can't break the URL but obspy is broken. I am happy to come and sit with you to look over things to see if it's anything I can help with.

URL query http://service.geonet.org.nz/fdsnws/station/1/query?station=A*&location=20 returns 12 stations

URL query http://beta-service.geonet.org.nz/fdsnws/station/1/query?station=A*&location=20 returns 109 stations

Python Obspy query inventory = client.get_stations(station="A*",location="20")

with regular client "GeoNet" linked to service.geonet.org.nz returns:
