Inherited my NZ grandfather's WW1 badges - help identifying please!

[Bungo]

Hi all,
I'm new to the forum. I collect medals, but I have absolutely no knowledge of badges beyond the very, very basic.

I recently inherited my NZ grandfather's WW1 medals, and along with them I received some badges that he brought back with him from the Western Front. Obviously he was a bit of a collector too! I don't plan to sell them, but I'm interested if any forum members out there can help me identify them and give me a rough idea of their values please?

I've attached a scan of the badges, along with descriptions and (where I can) my ideas on what they are. All are WW1 vintage and have been sitting in a drawer for the last 95-odd years:
A. NZ regiment colour patch - from pith helmets or some kind of headgear maybe? What regiment?
B. Sergeant stripes - NZ I assume?
C. Royal Marines collar badge
D. Grenadier Guards collar badge I think?
E. Royal Horse Guards collar badge
F. Royal Navy button?
G. Unknown badge - text "YPRES" under I assume the city crest. Belgian army badge, or a commercial souvenir?
H. I think this is a Reservist cockade from a German feldmutze cap - colours seem to be Wurttemburg, red paint in centre is in good condition, black paint around the outer mostly worn off. Reservist cross in centre.
I. Ribbon for German Iron Cross. I wonder how he ended up owning these two German souvenirs?
J. "NZMR" shoulder tab - New Zealand Mounted Rifles I think?
K. NZ 13th Reinforcements badge, "RD.812" in small type - I know nothing about these next few NZ badges...
L. NZ 11th Reinforcements badge, "RD.812" in small type.
M. 20th New Zealand badge - crest around bird reads "Kokiri Kia Maia"
N. NZ XIII badge, scroll at bottom reads "Kia Pono Tonu"
O. NZ Reinforcements badge, centre scroll under upright lion reads "Boyes Ferme" or "Soyes Ferme".
P. "1st Canterbury Regt" on brass scroll, "Ake Ake Kia Kaha" on silver base, silver bird at top.
Q. "NZ XXV" on scroll, upright Maori figure above.

Any help you can offer will be hugely appreciated! I suspect some of the NZ badges in particular might be hidden gems or rarities? If you need higher resolution scans of any, please just ask.

Thanks,
Bungo
