If the transformer neutral is not earth then there is no
direct path between these and therefore should not have a
voltage. But this is in a perfect world.

In reality the insulation in the transformer is not
perfect. It will have weak spots in it. When you connect a
meter between the earth and the neutral you are measuring
the voltage between the neutral and the weakest spot in the
insulation. You will find that if the insulation is good
there will be very little or no current flow if an ammeter
is connected between the earth and the neutral.

I have experienced this and have investigated to determine
why it is happening.
