My parents are in Christchurch and they were wanting to move back. They struggled to sell their place in NZ so it's on hold at the moment.
I wasn't keen on the move, access to decent healthcare being the main concern for them. The quality of living is better in NZ too.
I remember us speaking about it a year or so ago. They're in West Melton iirc? I'm just outside Lincoln. Houses are still getting snapped up here very quickly. Very diserable area being 20min from Christchurch. Same with West Melton. Brits seem to congregate in these two areas.
We're potentially looking at renting out our place (or selling) so we can always come back if the move don't pan out.
