Mr Smith was impressed with only a handful of submissions.
"By and large, I think there's a lot of bad designs in there that I would not be proud of flying."
He joins artist and Rangitikei District Council member Richard Aslett as locals who have put in designs.
Mr Aslett's flag draws on the traditional Southern Cross, tino rangatiratanga and the sporting silver fern.
The Flag Consideration Project began this month with the public invited to suggest flag designs. The period for suggestions will close on July 16 and a panel will select a shortlist of four designs in September.
As of Wednesday morning, 2133 designs had been suggested by submitters in New Zealand and overseas. A postal referendum in November and December will determine the preferred alternative flag.
