Any contruction jobs in germany im a new zealander?

Question

will do any construction work i can weld

Answer 1

There is a high demand for certified (!) welders, best ask at a temping agency like Manpower or similar. The might be interested in sending you to work all over Europe though, so you need to be clear that you have only WHV for Germany.

Answer 2

Go directly to a firm and ask if you could start there, to show how you work.

Another opportunity would be a agency for temporary work.

For workers who can weld is sure a demand.
