He is man for behind the scenes. If a rugby match was a film set, he would be the man moving the set around rather than reading the lines.
Not that he complains.
Reddish is a lock - for him, his job is about hitting rucks, winning the set piece and helping his side get a victory.
''I'm not really a too out-there sort of person. I like to get in there, do my work and get out of there,'' he said.
''Personally, my role is as a grafter and grinder, cleaning the rucks and just doing your day job. If you are spectacular and score a try then that is all well and good. But it's not something I am for.''
The try-scoring statistics back up Reddish's game.
In 30 games for the Hurricanes in four seasons, he did not score a try, and he has scored just three tries for Wellington in his half-century of appearances for the side from the capital.
Not that he is losing sleep over it - ''Not my job. I'll leave it to the fast guys.''
Reddish, born and bred in Wellington, is enjoying his time in the South, and has signed on for two years.
He said the change in surroundings was good for him, and he was glad to get the call from coach Jamie Joseph last year.
''I was not getting too much game time up there [at the Hurricanes]. I was looking at other options. Jamie hit me up and asked me about coming down here.
''I'm loving it so far. My wife [Rachel] went to university down here so she sort of knows the place. It's nice and easy to get round.''
Reddish, who has just turned 30, said Super rugby was much the same at different franchises although the closeness of the players in the South was something different.
''Down here we do not have the stars as up there, so there is a few less egos floating around, which is a good thing. There are subtle changes here and there but it is basically the same.''
Reddish, a qualified builder who is father to 11-month-old Annie, said he was hoping to crack the starting side but competition was intense.
''Tom Franklin and Joe Wheeler have been both going well. Coming off the bench, you are more about just trying to execute your role a bit quicker than those other guys who are getting a bit tired.
''If you go outside the system, you stuff things up, so your next phase does not work.''
Reddish will begin tonight's game again off the bench against the Stormers.
It is expected to be a physical encounter - they always are against South African teams - and Reddish will undoubtedly get some time out in the middle.
The Highlanders do not have a great record against the Stormers. They have not beaten them since 2007, losing six straight games to the Cape Town-based team.
Slow starts have been a feature of the Highlanders' performances so far this seasonand they can ill-afford another one tonight.
The Highlanders have been helped by the Stormers resting skipper and No 8 Duane Vermeulen but the visitors will still pack a punch on defence. They have lost just once so far in this competition and are coming off the bye.
The Stormers have been in Queenstown all week and arrived in Dunedin yesterday.
