A measurement of the β-delayed α decay of N16 using a set of twin ionization chambers is described. Sources were made by implantation, using a N16 beam produced via the In-Flight Technique. The energies and emission angles of the C12 and α particles were measured in coincidence and very clean α spectra, down to energies of 450 keV, were obtained. The structure of the spectra from this experiment is in good agreement with results from previous measurements. An analysis of our data with the same input parameters as used in earlier studies gives SE1(300)=86±22 keVb for the E1 component of the S-factor. This value is in excellent agreement with results obtained from various direct and indirect measurements. In addition, the influence of new measurements including the phase shift data from Tischhauser on the value of SE1(300) is discussed
