Thatu2019s a very bad situation.From what I know, NZ immigration takes two things extremely seriously.If you lie to them and they will find out.If you overstay and become liable to deportation.For the immigration, u2018Bona fideu2023 is understood as the requirement u201cto be genuine and to act in good faithu201d. In other terms, it means that:you genuinely intend a temporary stay in New Zealandyouu2019re coming to New Zealand for a lawful purposeyouu2019ll comply with the conditions of your visa once in New Zealandyou wonu2019t remain in New Zealand unlawfullyyouu2019ll be able to leave New Zealand at the end of your stay(source: Bona fide | Immigration New Zealand)By not leaving NZ, you have actually proven that you cannot be trusted and there is ZERO chance you will get any visa in the future. As a matter of fact, there is a significant chance that you will get to immigrationu2019s black list that is shared with other countries (e.g. Australia) and you will not get a visa there either. I am sorry.Note: I am not an immigration adviser or officer and all the above is based on my own experience as a NZ immigrant and stories from people around me.
