After receipt of the Planned DG Summary I verbalized we would need the Final DG Summary before pushback. When it came time to push I forgot about it and subsequently pushed without the Final DG Summary. After push I remembered the DG but was now on an active taxiway at a busy airport so I decided to taxi while waiting for the DG and weights. That probably compounded our problems because it turns out the reason for the delay of the DG Final was there was a loading issue.During taxi when the FO (First Officer) called Operations to inquire about the DG and final weights we were told they needed to rearrange some luggage in the pit that was adjacent to the DG. We were directed to a hardstand where this was accomplished. We then received the Final DG and weights and continued the taxi.
Both Captain and I discussed and agreed on a requirement for final Dangerous goods paperwork at international station prior to pushback. However; just few minutes later; after all doors were closed; we called and received pushback clearance without the final Dangerous Goods paperwork.During taxi we called Operations to get the final Dangerous Goods paperwork and little later we were requested to stop at the hardstand to allow Ground Crew rearranging cargo and bags.
Air Carrier flight crew reported gate departure without required Hazmat documents. Flight discontinued taxi temporally to reconfigure Hazmat cargo and obtain the missing Final Hazmat documents and subsequently departed safely.
