The 22-year-old Southern Steel goal attack is preparing to face her former team, the Mainland Tactix, in Invercargill tomorrow afternoon.
Fenwick is in the early stages of her second stint with the Steel, having previously played for the team in 2011, the year after debuting for the Tactix.
She only made one brief appearance off the Steel bench in 2011, before heading back to her home-town Tactix for the past three years.
''There has always been a rivalry with Otago and Canterbury,'' Fenwick said.
''But there is even a little bit more when you want to prove yourself a little bit.''
Fenwick spent the majority of the 2012 season out and made just 17 appearances in her four years in Christchurch.
She was not re-signed by the Tactix after last season, allowing her to join a youthful Steel roster.
''The change of environment has refreshed netball a bit,'' the 1.81m goal attack said.
''It can get a bit same old, same old sometimes. It's nice to come into a group of girls that are excited.''
Fenwick, one of six Steel players based in Invercargill, trained in Dunedin on Wednesday with the rest of the team.
In addition to training on court, the team had a film session, one to which Fenwick thought she and flatmate Jane Watson, who also played for the Tactix the past three years, could contribute.
''I was watching [the Tactix] on Monday night and it was quite different,'' she said.
''They were using their subs a lot. There were a few different people in there. It's interesting.
''We watched the game and noted down a few things.
''Once we get into the analysis, we will be sharing that around.''
While the Tactix lost to the Northern Mystics on Monday night, the Steel is also coming off a season-opening 68-62 loss to the New South Wales Swifts in Invercargill.
Like the rest of the bench, Fenwick did not get any court time, but saw positives from the match.
''We just let it slip a little bit at the end. I think we did it to ourselves,'' she said.
''But we really did stick it out most of the game, which was nice to see.''
Fenwick's move to the Steel reunites her with coach Janine Southby, her New Zealand under-21 coach from 2010 to 2013.
She made the age-group team as a 17-year-old, the year after making the national secondary schools team in 2009.
I know [Janine] quite well,'' Fenwick said.
''With the under-21 environment, you aren't around everyone all the time because everyone is based around country.
''Now, to see her often, it's nice to have her help me and develop me more.''
While she did not get any court time in the team's first match, Fenwick knows what she wants to get out of this season.
''I really want to grow myself. Just get my consistency and confidence,'' she said.
''Just be able to put it out there and be a force to be reckoned with.''
