This sample provides a unique analysis of the mass-metallicity relation (MZR) over an extended redshift range using consistent data analysis techniques and strong-line metallicity indicator. Over the redshift range probed, we find a constant slope at the low-mass end of the MZR, which is however significantly steeper than seen in the local Universe. In this range, we can fully describe the redshift evolution of the MZR through the evolution of the characteristic turnover mass where the relation begins to flatten at the asymptotic metallicity. At fixed mass and redshift, our data do not show a correlation between the NII/Ha ratio and SFR, which disagrees with the 0.2-0.3dex offset in NII/Ha predicted by the "fundamental relation" between stellar mass, SFR and metallicity discussed in recent literature. However, the MZR evolution towards lower NII/Ha at earlier times does agree within the uncertainties with these predictions.
