Help! Residency partnership

I am a nz citizen and have just applied to support my partner to get residency. We have lived together for two years and have one child together and one on the way.
My only worry is that in the past I have supported an ex partner in getting a one year work visa. Could this affect our application?

I believe there needs to be a 5 year gap between sponsoring partners. Not too sure if that also applies to sponsoring a work visa tho... Good luck!
