help with moving to Christchurch

Firstly, my family are everything to me. I would like to give them a new head start in life. We moved into our rental home 2 years ago, and was offered a long term tenancy with a private landlord. After the first week there was a huge water leak in the bathroom, which wrecked the flooring which after time became unstable. The Landlord was informed, and instead of fixing the issue, he issued 3 months notice for us to be out of the property. I am recovering from Surgery and took a desk job because I couldn't work in my normal job as an Electrician. I took a substantial drop in pay. Our eviction could not of come at a worse time, as I have four children all in school. I cannot afford to move out, I cannot afford to move my children. I have begged with the landlord, but he refuses to listen. I have tried all avenues to find help, and this is the last resort. My sister has offered to look after us for a few months until we get back on our feet. I would like to take my children to Christchurch to be around my parents where we can have support from my family, this is a huge move for them, they have to give up everything. Many thanks for your help.
