I think that I am going to buy the daiwa 5000BG finally and spool it with 60 lbs line !

Does it seem a good choice to you ?

I will not be targetting huge kingfish so it should be enough !

As said before if I plan to cast all day long I don't want something to heavy :)

For the lures I think that I will buy one or two here in France and the rest in Auckland when I will arrive !

I have another question : if I want to cast far enough from the rocks to catch kingies with a 60lb braid what is the minimum weight of a lure for you ?

I was thinking of not taking lures less than 50 grams !

Of course it will depend mainly on the rod. So which rod would suit this reel and braid ?

A 15-24kg rod ?

I don't know if I am clear enough sorry...

You could absolutely bait fish for Snapper with a stickbait setup. As either a heavy strayline rig or maybe livebait; might have a hard time sneaking the livebaits past the Kingies though if they are around.

Denim I don't really know what to buy as a rod but I would like not to spent more than 200 to 250$ ! I saw the shimano backbone for example is that good ?

Of course I am not planning to catch 20kg + kingies as I am not enough experienced !

Even less than 10kg kingies would be great for me !

The biggest fish that I caught stickbaiting was an 8 kg GT in andaman islands !

Here in France we have seabass but nothing to compare with big pelagics fish !

In France I do a lot of seabass lure fishing and I know that sometimes you can fish for hours without catching anything even on the spots that you know to work at this specific time / conditions !

But when you catch a fish all the hours spent for nothing are gone !

I am also going to take my 3000 reel with me for softbaiting and micro jigging and i will buy a softbait rod too in NZ ! (but this is not the topic)

Do you think that with a stickbait combo with a 5000 or 6500 daiwa BG I will also be able to be bait fishing for snapper from the rocks ? (even if I know that this combo will not be the best but I don't want to spend too much money)

I am going to look for cheap Orion lures here which one would you advice for kingies ?

Which size of lures do you guys generally use for land based kingies ?

Daiwa 12 braid seems really good but really expensive too ! I don't want to spend too much as I am a backpacker fishermen ;) In fact I am planning to buy a van also to visit your beautiful country so saving money really matters in my trip !

Denim I would be very pleased to go fishing with you of course ! :)

Even if colours really depends on the conditions do you have some basics that suits most conditions ?

In France for example we use 

- white colour lures at sunrise, sunset or when the weather is really cloudy / stormy

- natural colours (blue, green, black) during the day

- flashy colours when the water is really dirty

Is that the same rules generally in NZ ? :)

Reel size - Unless you're going for absolute monster kings in the 30-40kg bracket, you don't absolutely need a great big reel. Something like a Daiwa 5000 should be plenty (depending on what line you put on of course). In addition to this, you want to be aware of how comfortable you will be casting with your set up. Casting with a heavy reel can be quite tiring. It sounds like you're casting from shore, which may mean that you're more than likely to catch kings in the >20kg range. Not saying that you can't catch bigger kings off the rocks, but saying in general, again before anyone gets angry, i am talking about in general. 

Braid - I'm not sure what everyone else uses but I use Daiwa Saltiga 12x or 8x braid and sometimes Varivas. Lines specifically designed for casting. I have 70lb on right now and have about 350m which is more than plenty for me. 

Lures - Not entirely sure what lures all of those are, but the ones I am familiar with, i.e. the rapalas should be fine. I'm not entirely sure that those are 'stickbaits' however. They may just be hard body lures which can and will work, but it's quite hard to go past the action of a good stickbait. As you know, they have a different action than your typical hard bodied lure. I love the action of my carpenter as well as my Hots Keiko. 

Colours - depends on the day, clouds, colour of the water etc. 

Season - depending on location they can be all around or very specific. Generally, they will appear around spring time like most other fish. You might encounter more rats during this time.
