I'm not sure if I'm using the best stuff for the right application but I use inox& inox lube, shimano star drag grease,abu oil of different weights and both corrosionX and reelX.
The last two were brought from the states but got the inox lube at The Big Fish Mount Maunganui and I can't remember which tackle porn store I picked the shimano grease up from but I know I didn't order it from over seas.
Also the guys at Big Fish have hooked me up with a few of my drag up-grades (I usually upgrade rather than replace where I can).
Don't know if that helps at all but my two cents.

I do not know if this applies in New Zealand, but I have read that using non-shimano grease in their reels is enough to void the warranty.

There is a long thread on tackletour regarding this

had a couple guys ask about lubes recently. it's a work in progress, so here's where i'm at now ......

for bearings, i have some "speed" lubes for the bass guys, but they don't get used much. i'm pretty much exclusively using corrosion x, but i keep it in a reel x bottle. that's been a point of some confusion. i started at the recommendation of my local tackle shop. it's worked well enough, so i've seen no need to change. the reel x is $5 for a tiny bottle, the corrosion x is $17 for a big trigger spray bottle. the math is easy.

for drag grease, i just switched to cal's drag grease and i'm very happy with it. i had purchased 6 pounds of shimano drag grease late last year and finally ran out. cal's grease is $24 per pound, shimano's is $80. the math is pretty easy here as well.

cal's grease also works great for the screw holes and other non-exposed metal surfaces. i am still using yamaha engine grease. there are four reasons here. first, i was told way back by my yamaha dealer that this grease had excellent salt water resistance. i've never questioned that claim but it seems to have held up. two, it's available in cartridges for mini-grease guns. you've seen my grease gun before. it's a life saver. three, it's dirt cheap, at i think $5 for a one pound tub or $7 for a set of three mini-grease gun cartridges. and forth, the stuff says blue forever. i can open up a reel five years down the line and see that i've been there before. that helps me quite a bit, because i like to know if a reel comes back with a problem.

and then there was my secret sauce. i was goofing around with a mix of corrosion x and shimano drag grease for a while. i was looking for a lube that i could use in spool bearings. the goal was more protection than simple corrosion x, and more spin than heavy grease. i got my best results from a mix of 1 part shimano teflon grease and 5 parts corrosion x. even these results were disappointing, so i gave up. i've come to the conclusion that bearings will simply not last forever. if i want a reel to cast, i leave the bearing open and lubed with corrosion x. if the reel is used for trolling only, then i pack the bearings with grease and reinstall the shields or seals. it's one way or the other.

hope this helps. alan
