Here's some rough chords for the verse and bridge that I think follow what John is doing (copy and repaste into WORD/TIMES/12 to line up chords):

C------------------------------------F-----C
On a cold Kaikoura (Ky koora) morn-ing
--------F---------------C--------G
When drizzle draped the land in grey,
------C----------------F-----C
And darker grey the head-land loomed
--------F----------------------C---G-C
Where surf thumped, snarl-ing up the bay;
---F---C-------F------------C
A gull flashed silver over rocks,
F--------------C-----------------------F----C----G
Fringed with white lace where the kelp beds heaved,
-----C---------------------F----C
And beauty lived in the drab and dark
------F------------C-G----------C
With-out a flash of co-lour re-lieved...


Bridge:

C----A#-----------------C
And who was Charlie Johnston then?
-----A#-------------C
Did Vernon Willis leave a wife?
Am--------------------G-Am
How did Robert Kit-to die,
------F-----------------------G
And Roy Frank Chapman yield his life?
------A#-----------------C
They were not seen at Alamein,
-----A#---------C
Bill O'Connell faced no gun,
Am------------------------------G--------Am
John Turich's hands worked iron and rock,
---F----------------G
A-longside Oscar Cottington.

Cheerily,
Charley Noble
