There appears to be a version change and 'extra' bits in the data. The file loads but when you zoom to the extents of the dataset it's telling you that you are outside the coordinate system for the National Grid? Here's the projection data at the top of the Manifold generated MIF. If I re-export this file from Manifold to MIF I get a file that will not reimport correctly into Cadcorp. This file imports into Manifold correctly and fits with other data provided I tell it that it's British National Grid.
#MAPINFO NEW ZEALAND SOFTWARE#
If I export a file to MIF/MID from our Cadcorp software I get the folowing projection details in the MIF file. I've had this problem for ages and posted about it over a year ago now. Perhaps the data is not being projected by MapInfo and simply dumped at the coordinates specified by the mif file? If I add additional data to the map window which is in NZTM, this seemingly aligns perfectly. Although MapInfo can import the file ok, when the projection is examined in MapInfo via Map > Options > Projection, it is defaulted to Lat/long. I have had similar and have been meaning to send this to tech for some time.
