Early reviews of the gun buyback process have been positive, with owners saying it was quick and easy.
Christchurch's Riccarton Racecourse is hosting the first event on Saturday, four months after the mosque attacks that sparked the changes.
More than 900 people registered around 1400 firearms online in advance of the event, which has so far gone smoothly.
One man, who wished to remain anonymous, said he was impressed and "definitely" happy with the amount he got.
"I was selling an SKS and I got $712 for it. It was in the near-new percentile - it was fine. Showed up, they got us through pretty quick," he told Newshub.
"They line you up, have a number, call out the number, do one person at a time. They've got a gunsmith on site and he goes through it. I reckon they're being fairly fair."
Another gun owner, Chris Williamons, said it was "nice and quiet and quite respectful".
"Some of us are quite sad we've had to give up our sporting [equipment]... I had two rifles. They paid me what they said they would, there was no argument, no hassles. I understand where it's all coming from."

A third man Newshub spoke to said there was a short wait, but the process was easy.
"I had no idea what I was going to get. Quite happy with the result - very easy, good, fast."
Gun owners have to bring their firearms licence, photo ID, bank account number and online notification number, along with their firearms and parts.
It's the first of 258 gun buyback events which will run across the country over the next three months.
Saturday's event runs from 10am to 3pm.
