oxidation occurs at the positive electrode, and reduction at the negative electrode. However, in a question it tells me that the electrode potential for Cu2+/Cu is +0.34, whilst for Fe2+/Fe it is -0.44. As the Fe has the more negative electrode potential it gets oxidises, hence I thoutght it would be the positive electrode. But the answer is that the copper electrode is the positive electrode?

yeah the answer is correct. The positive electrode is always where reduction takes place.
