NZ Coastal Seafoods - Ngāi tahu seafood?

Ok

I have tried to find the physical address for NZ Coastal Seafoods and on their website it comes up with the following:

7 Bolt Place, Harewood,Christchurch 8053
https://nzcs.co/contact-us/

When I jumped on google maps I could not find the place with any signs of NZ Coastal Seafoods, but what i did find was the big warehouse with the name Ngāi tahu seafood located on the same street (next to 7 bolt street) and the address for Ngāi tahu seafood on their website is

6 Bolt Place, Christchurch Airport, Christchurch 8011, New Zealand
https://www.ngaitahuseafood.com/contact/

I also went on https://www.seek.co.nz/jobs?keywords=Ng%C4%81i%20Tahu%20Seafood%20 and found a number of jobs advertised by Ngāi tahu seafood in the last 12 days. Looks like Ngāi tahu seafood business is growing similar to NZ Coastal Seafoods which are physically located next to each other.

Now my question is Ngāi tahu seafood same company as NZ Coastal Seafoods, or is there any connection between the two.
