The 16-year-olds have been skiing and riding at Cardrona for about a decade.
Porteous said it was ''insane'' to be back.
''I actually came here first when I was six months old, and had a day in the daycare. I've probably been really properly skiing here since I was 6, probably even younger than that,'' he said.
Emotion got the better of him when asked about the influence of his mentor, Tom Campbell, Cardrona's former head terrain park builder who died in a car crash on the West Coast last year.
''The legacy that Tom Campbell built up here, the standard of parks has really changed the mountain in a lot of ways,'' he said.
Sadowski-Synnott agreed.
''I'm so thankful for what we've got up here and it's cool because it's accessible to everyone, and everyone can ride here and watch everyone else riding,'' she said.
They were excited about today's street parade in Wanaka and looking forward to catching up with their friends.
''I'm so excited. I think it's going to be really cool. I hope a lot of people turn up, but look, I'm just stoked, absolutely stoked,'' Porteous said.
Sadowski-Synnott said her friends had kept in contact with her while she was competing and had informed her of the massive support she was receiving at her school, Mount Aspiring College.
''My friends sent me Snapchats and even on the days that it [competition] got postponed they were waiting to see me [compete]. That was really cool to see. It really got me pumped up,'' she said.
Sadowski-Synnott will not be in Wanaka long as she travels to Colorado to compete in the US Open next week.
What about Porteous?
''Um, I think Mum wants me to mow the lawn,'' he said.
The Wanaka parade will begin at 3.30pm.
