Where to go when your SCV has been declined?

I'v got criminal convictions. I filled out and sent the disclosure form in and the following week got my answer that I'm not of good character and am only allowed to apply for a tourist visa. My convictions were 2007-2006 assault and the rest 1999 jailed for 6 months served 3 for good behaviour on drinking and driving. My question is: is there a way around this? Can I get it reviewed? Is it worth getting reviewed? I want to move with my wife and four kids. We all hold NZ passports...do I just move over and tick no on the form?
