Around a grand or so for tuning, depends on who you go to etc.
The cert would only be if you want to run the Rally Coil-overs that are with it. Has some normal (inverted strut) suspension with it though too, so can just throw that back in and not have to worry about it. All legal though, WOF'd Reg'd etc.
And just down in Dunedin so not all too far away.
Not sure if I mentioned, it's a GF8 V2.
Off the top of my head:
Rebuilt late last year with full genuine seal kit, new timing belt, water pump, tensioners, pullys etc
TD05 Turbo
Link G4+
2 sets of suspension (one set inverted strut, slight lowering springs, another set is adjustable Revalved suspension for rallying)
3 sets of wheels, all factory with Road tyres/Rally Tyres/Snow tyres
Front upper and lower bracing
Parallel fuel rails
Rising Rate FPR
DW200 Fuel pump
Sump guard (just visible in the first photo)
probably a few other things I've missed...
