Hi Matt, and welcome along!
Plenty of love for the e30 here.
In the pre-lockdown world the Welly Crewhad frequent family-friendly coffee meets, brunches, cruises, or long-distance trips, and a monthly social night at the 1841 in J'Ville (BMW Car Club NZ, Bimmersporters and BMW enthusiasts welcome). You might care to take a look in the Wellington room and click 'follow' so you get notified when things are happening; you'll certainly be welcomed. I'm sure that in post-lockdown NZ we'll be able to get back to socialising with our mates and cars.
Looking forward to seeing the pics.
