The 21-year-old has recently broken back into the first team after a four-month absence and has started the last three matches, even finding the net for his first strike of the campaign against Blackpool.
But his contract runs out at the end of the season and Smith admits his future with the Championship club is unclear.
“I haven’t really spoken to the manager about the contract situation,” he says.
“There is a little bit of uncertainty as I want to play as high a standard as I can and you want the security of knowing you are going to be playing football next season. I want to be part of the first team plans and if I am, I would be delighted to stay.
“First and foremost in my mind is to try and stay in the team, do as well as I can for Ipswich and if they offer me a new deal, happy days.”
The 1.88m centre back was born in England but spent much of his childhood in New Zealand and attended Westlake Boys High School on Auckland’s North Shore before joining the youth academy at Ipswich.
He played for the country of his birth at age-group level but switched allegiances to New Zealand prior to the 2010 FIFA World Cup, during which he played every minute of the All Whites’ three drawn matches.
His professional club career has also included loan spells at Stevenage, Brentford and Colchester United.
Should he stay at Ipswich beyond this season, Smith may find himself in a lower division as the Tractor Boys lie just one place above the relegation zone in the second-tier Championship and face a fight to avoid the drop.
