SNZ are not able to comment on the matter as it is now going through a formal process. Ten places for the fields of 25 in Rio were on offer at the worlds last year, and another 10 at the Portugal qualifier.
Radford finished 20 seconds off the last qualifying spot, and about 34s behind the winner.
Swimming's governing body Fina offered one extra quota spot to each region, the Americas, Africa, Europe, Asia and Oceania for countries not already qualified. That would fill out the fields to 25 in each race in Rio, on a one swimmer per country basis.
That equated to a gimme for SNZ to put forward Radford's name to the New Zealand Olympic Committee.
In past years that might well have got Radford a trip. However the NZOC attitude these days is hardline on qualification.
Two elite New Zealand sailors, board sailor Natalia Kosinska and Laser Radial athlete Sara Winther, recently appealed to the Sports Tribunal over Yachting New Zealand's failure to nominate them for Rio.
The tribunal rejected their appeals but was critical of YNZ's treatment of the pair.
