Most applicants for residency visas in NZ have experienced very long time frames for their visa processing so it isn't unusual for someone to be in the system and processed for 8 months. Having said that, you can lodge a complaint against your CO if you feel like it, but the outcome would be unpredictable and may not expedite your visa application. It may even cause further delays.
You can consider contacting the manager of the Auckland branch or the section head of the CO. You may also lodge your complaint against NZIS direct by going to

I am trying to understand your situation and I do believe you are very worried for your wife and child as the situation in Egypt is very unstable. Hence you are very emotional and angry. It doesn't help you here as people do try to help but are completely put off by your tone. Also calling your CO names and berating them isn't helpful either. You will end up without anyone helping you at all, driving people away.
If you feel that your situation is desperate and your wife, child life is in danger and you can prove it, I would suggest you approach your Member of Parliament (MP) for assistance. There are also various humanitarian organisations in NZ which may be able to direct and assist you better.
