pix4d vertical co-ordinates

I've been given Ground control points for job and the vertical co-ordinates are in AHD (Australian Height Datum) Does anyone out there have any idea how to transform vertical heights in AHD to Pix4d accepted vertical co-ordinate system e.g. MSL emg88 or 94 or08. Also I have access to ArcGIS, QGIS etc for transformation etc..
