"I think so, if the technology is there," said Taylor, who guessed it was a "funding issue".
"If it was there it might have saved me, or showed I hit it. I didn't feel anything."
A 39-run fifth-wicket stand between Tom Bruce (22 off 15 balls) and Taylor (25 off 11 balls) had given New Zealand late hope.
Pakistan coach Mickey Arthur described Amir's over to Taylor as "pivotal" but believed Taylor was out.
"Yeah. There was certainly a (snicko) spike, you've got to say he probably did," Arthur said.
New Zealand coach Mike Hesson was more circumspect.
"The spike obviously occurred at the right time, but without hot spot it's difficult, and they rely on RTS (real-time snickometer)," he said.
"My personal view is that to overturn a decision I'm not a huge fan of only one bit of technology, but that's life."
A New Zealand Cricket spokesperson said in the agreement with Sky, hot spot was scrapped for the West Indies and Pakistan T20 games to save money.
The overall Decision Review System was introduced for T20 cricket last year. Authorities had previously said they wanted to avoid delays in games.
Following the Tri-Series, New Zealand plays five ODIs against England then tests at Eden Park and Hagley Oval.
