Rust repairs in Taranaki?

[Marco Polo]

Hi all, not having lived here long enough to know, any recommendations for a reputable person/business in the New Plymouth area to repair a couple of holes and soft spots in my L200 cab? I want it done properly but doesn't have to be show quality. Hasn't gone for a WOF yet but it will fail in its current state. P.O. did a marvelous job of covering it up, last WOF guy didn't even notice!
Would love to find a competent old school panel beater that I can get on with as I have an old Sunbeam in the shed that will need some attention too.
