Jarvis joined Norwich on transfer deadline day after finding himself out of favour at Upton Park.
The former Wolverhampton Wanderers winger struggled to hold down a regular place in Sam Allardyce's side last season, and West Ham's summer signings have pushed him further down the pecking order.
The arrivals of Victor Moses on loan from Chelsea and Michail Antonio from Nottingham Forest increased competition for places in the West Ham starting XI, and Hammers boss Slaven Bilic was happy to loan out Jarvis.
The England international marked his debut for Norwich last weekend with a goal in the 3-1 win over fellow Premier League new boys Bournemouth
The 29-year-old has made an instant impression on Neil, with the Scot saying that the flying winger is the type of player he wants at Carrow Road and that their association could be extended at the end of the season if he continues to shine.
"I had a good chat with him before he came here and what I need is hungry players who have a point to prove," Neil told the Pink 'Un.
"There is no use coming here to pick up their last pay cheque because that is no good to me. We are going to be a hungry group who are going to fight for every point.
"At the moment it is just a loan deal. We'll see how he does and he can have a look at us and we'll take it from there. There is more to come because he has not played regular football, although he had five pre-season games and then was a bit of a bit-part player so he has not played a lot recently."
Neil will be hoping that Jarvis, with a regular run of games, can recapture the form that earned him a call-up for England in 2011 during his time in the Premier League with Wolves.
