"I can still see people heading out for a ski... It's definitely a good turn out for the first day, people aren't used to skiing this early in New Zealand."
McIvor said it would take awhile for people to realise Happy Valley was open to the public, but seeing a healthy crowd today was "just awesome".
At 2.30pm 826 people had walked through the lift gates to enjoy the snow.
He added it was a good opportunity for beginner slope riders to learn before the field got busier later in the year.
The field usually looks pretty bare at this time of year, McIvor said.
"If we didn't have this piece of technology we definitely wouldn't be able to do it".
Newly purchased carpet lifts are also set to open when conditions allow.
The Valley's "Snow Factory" also blasted a snow pile into the Happy Plaza for guests who weren't skiing or snowboarding, so they could get their first touch of snow for winter 2017.
Mt Ruapehu chief executive Ross Copland said he was "extremely proud" of the work his team had done to transform the valley to open over the long weekend.
Copland said it was a unique opportunity for locals and visitors to ski and snowboard over Queen's Birthday Weekend.
