A seven-wicket win in the opening Twenty20 cricket international against India has made a world of difference to New Zealand who go into the second match here on Friday with their tails up."Hopefully this is the start of something," said captain Daniel Vettori, sounding more confident than when he described India as "a huge challenge" before the start of the series."It was a really pleasing win, they put us under pressure and we responded well," said Vettori.But Indian skipper Mahendra Singh Dhoni did not believe the result was a pointer to how the rest of the series would go, with five one-day internationals and three Tests to follow the second Twenty20."You can win a game by a big margin and quite convincingly but now it's a fresh start," Dhoni warned."We've learned a lot from our mistakes, and we learn quickly. I think the New Zealand team knows if we don't make mistakes in the next game they will have to chase a big score."India's power hitting ability was on display from the start of the first game with Virender Sehwag belting Tim Southee for three consecutive sixes in the opening over.But Vettori was pleased with the way his bowlers were able to recover and restrict India to 162 for eight and the New Zealand batsmen reeled in the target for the loss of only three wickets and with seven balls to spare."I thought it might be the first time I've ever chased 300 in a Twenty20," Vettori joked."It was a reasonably daunting start. We knew India have got very good players and it's up to us to back ourselves continually. We have got to be so precise to get through that initial (batting) onslaught."
