This year's achievements will be recognised at next year's ceremony, scheduled to take place in November 2021.
"It was a tough decision, but it was the right decision," Jonas.
He said the 2021 Sports Awards would also feature Masters Team of the year for the first time, for an outstanding performance by a team in masters-level sport.
"That's the result of feedback from the community, which is awesome, and reflective of our wider sporting family.
"It is important that we do celebrate success and celebrate amongst our peers, and that was definitely loud and clear.
"The work will still go ahead around collating the 2020 nominations, and we do encourage the codes to put those nominations in, because we're only as good as the information we get."
The nomination form for 2020 will be accessible at www.sportwhanganui.co.nz
