I have since realised that it is not logical to modify the spatial data in this way as it would break the regularity.
Change projection of netcdf data and convert from UTM to lat/lon

I have a netcdf file
vardata=ncread('TL__Map1_15C_sand1__20mres_-36.265137N_174.790466','TLdata');
ncdisp('TL__Map1_15C_sand1__20mres_-36.265137N_174.790466')
Source:
X:\Matlab Scripts\TL__Map1_15C_sand1__20mres_-36.265137N_174.790466
Format:
netcdf4

I know that the projection is WGS 1984 Mercator 41 and the lat/lon coordinates are in UTM.
I would like to be able to convert this grid to lat/lon, can anyone help?

Could you provide more insight on this issue of yours regarding lat/lon array of different sizes?
