Thank you everyone for taking the time to write considered responses, I do appreciate them all, and especially the honesty within the posts. It’s important for me to know the negative aspects as well as the positives.
A few people have addressed the issue of having children in NZ and then not being able to leave with them, should I wish to. This is something that does worry me, and whilst I hope that we would be able to have a happy marriage and family life, and that no one hopes for their relationship to break down, these things happen. It needs to be a consideration, however scary it is to think about.
grumbleina your posts are very helpful, thank you. The information about housing especially so. My DP’s Dad is actually a builder by trade, so hopefully we wouldn’t be caught out there, but I will absolutely ask DP about the leaky homes thing. I had no idea that a dehumidifier would be so important either! A trial run is a great suggestion too, and thankfully I can drive - I’ve heard that the public transport in NZ is very sparse, which would be a big shock coming from London!
Underthedeepbluesea your post made me chuckle because my DP is from South Auckland! His parents still live there. I did have a brief look into Dunedin and it looks lovely, and I can see what you mean about the property prices too. I think my DP was thinking Wellington partly due to the house prices and being able to get more for your money, and also because work-wise it could be a good location.
Toastedorfresh I’m sorry to hear about your experiences and I hope that things begin to look up for you soon 
specialsubject your post made me laugh, especially about my mum not appreciating a lunchtime call, and drivers randomly bumping into each other all the time. I do love cycling, and we have done lots of cycle-touring in the UK and Europe, and I would love to see NZ by bike. I didn’t know Wellington was directly on a fault line; after seeing the devastation the CHCH earthquake caused, that is a worry.
Shutuplegs thanks for the insight into your relationship with your sister. The losing touch and not being able to see each other in person would definitely be a big factor.
Gennz thank you for your post. It is amazing to me that you can swim outside in October! It is very useful for me to hear about the school system too, as I have heard a little about the decile system in NZ but wasn’t sure what it meant for the bigger picture. Rationalising the travel issue as being a day away, a horrible day but only a day was also very helpful and heartening for me. I hadn’t really thought about it that way. The expense and the jet lag is a big downside though. My DP is from South Auckland . Could I ask the reasons why you wouldn’t consider living in Dunedin or Wellington? (Just curious!)
Neenawnee I don’t know either, I suspect that Gennz is correct. I don’t know how relevant this is, but should we have children, we would want them to hold both British and NZ passports.
TheCrimsonQueen no problem, thank you for your honesty. I’m sorry to hear you experienced such racism.
ByronBaby thanks for the informative post. It is a great help to hear your pros and cons. I would definitely miss pubs! It’s interesting you are an artist, and I’m glad you have found some success with your work. My work is also in the arts sector (different field) and the kind of word of mouth thing would be important for me. Your last sentence made me laugh out loud, so much so that I had to explain to DP why I was laughing. It made him roar as well!
Athrawes I’m so glad you love living in NZ. The kayaking so close to your house blows my mind!
Kiwidoc congratulations on your baby! It’s useful to know that it took you some time to settle in and feel more at home there.
Dontevenblink thank you for your post! It’s helpful to have some insight into making friends and joining in with the community.
TwoLittleTerrors I’m horrified at your experience of racism in NZ.
Notstayingup thanks for telling me your story, it’s so interesting. Do you find it reasonably do-able to visit NZ every year in terms of finances and logistics? (If this is too personal feel free not to answer). If I was living in NZ I would want to visit the UK yearly.
Thank you so much for all the useful replies, I have read carefully and appreciate each one. There is a lot for me to think about here, but the personal experiences both good and bad are so useful for me. Sorry for the epic essay – it’s taken me so long to write it I had to save it in a word document!
Cheers all
