Well, I decided to check and to be honest, it's not clear.
The nice lady I spoke to on the main engineering number I found (shown below), informed me that:
1) they definitely did do ad-hoc work in the past
2) she's not sure if they still do ad-hoc work now

Air New Zealand Engineering Services
634 Memorial Avenue Burnside Christchurch City Canterbury 8053
P O Box 14005
Christchurch Airport
(03) 3747000 Fax:(03) 3747668

Apparently you'll need to speak to someone in marketing - I really don't know why someone in marketing is the person you need to speak to for engineering work, but that's not the point.

The best place to start is apparently a guy named Trevor Lee, in marketing on 03 3747015.

You will need to clarify if they are still accepting ad-hoc jobs. They definitely used to, but they might not any more.
I would still recommend them over anyone else, until it's verified that they don't do it, as their standard of work is very, very high.

That's as much help as I'm going to offer...good luck and I hope you end up with a good job - whoever you end up with.

Thanks Muz, way above the call of duty! Will get onto them myself and see what happens. At least it's been pants weather so I don't feel too bad about not riding!

I had a crack forming around the down tube / seat tube connection to the bottom bracket. I dropped this off at Thorpe today so will see how it goes when it comes back. For the note he has moved to Boundary Road out by Rangiora (https://yellow.co.nz/y/thorpe-engineering-dalgety). Indicative cost was $100. so if I get another year or 2 out of the frame not a bad investment I thought.

What's the frame and what grade of aluminium?

A good welder is very important, but the good welder needs the right info to get a good long term result.
It's vital the welder uses the correct filler rod and then you need the correct heat treatment. Get it wrong and aluminium ends up with the impact strength of cardboard. Get it right and it's as strong as new.

7000 series just needs welded and then artificially aged (unless you want to leave it a year). 6000 series needs solution treated, quenched and then artifically aged.
