The competition, launched by Specsavers and New Zealand Cricket, runs from November 19 to January 28.
Graeme Edmond, Specsavers New Zealand managing director, said the company has been supporting domestic cricket umpires since 2010 and this competition is an opportunity to reward those who volunteer their time to cricket throughout the country.
Six finalists will be selected from around the country and from this group the national winner will be announced.
A range of prizes are up for grabs, including tickets to this summer's International ANZ Series featuring the Black Caps against England, $1000 spending money and a one-on-one training with a top New Zealand umpire.
All those who nominate someone via the Specsavers NZ Facebook page will receive a voucher for $50 off any pair of Specsavers glasses.
Nominate your favourite local umpire by visiting facebook.com/SpecsaversNewZealand or getting information from your local cricket club.
