Gate scored three personal bests on his way to victory and was delighted at his form so soon after returning from a six-month road racing campaign with the BikeNZ under-23 squad in Europe.
"It takes a bit to adjust back to the track, although you can simulate it on the erg. It's takes a bit to get the feel of the track again,'' Gate said. "I am thrilled to get my first individual national title and really pleased to get three big personal bests in the timed events.
"To get those times over the shorter distances was a complete surprise with such little experience. It's reassuring, really, and I am excited about the track season coming up. I think it goes to show how productive the campaign has been in Europe and that the international competition is showing dividends.''
BikeNZ high performance director Mark Elliott said the two-day omnium proved an ideal early season test of the country's leading riders.
"We wanted to get some information on where our riders are at in terms of short and long term power, and their overall fitness,'' Elliott said. "As a fact-finding exercise it has been excellent and now we will be evaluating and letting riders know what they need to work on in the next month leading to the Oceania Championships.
"We want our riders to be putting up their hands at that stage towards the London Olympics.''
The men complete their camp this week with the endurance women's squad and sprinters coming in for testing over the next week.
