At a recent uniform fitting in Wellington, marchers were shown how to wrap the puttees correctly, a task Mr Bird said could be tricky even for the most experienced of soldiers.
William Matheson who is in the Air Training Corp at Trentham is one of the 30 who will march in the replica uniform. Mr Matheson was looking forward to honouring the soldiers who went before him including his great grandfather, Donald Munro Matheson, who was in the 1st NZ Light Trench Mortar Battery.
"It's special to wear this uniform and remember those from WWI."
The Rimutaka Re-enactment March will be held on Sunday, September 27.
Of the 250 marchers, about 160 are direct descendants of soldiers who trained at Featherston.
Other marchers are made up of cadets and members of the New Zealand Defence Force.
The marchers will set off from Camp Road just north of Featherston at 3am.
