The New Zealand census treats Maymorn as part of Te Mārua for statistical purposes.

The usual resident 2013 population of the Te Mārua area was 1,152.

The area has a tranquil setting and consists of lifestyle blocks and farms surrounded by hills that are usually covered with a dusting of snow in the winter.

Because it is marginally populated, the area is best known for the Maymorn railway station, which is on the Wairarapa railway line between Woodville and Wellington and served by the Wairarapa Connection daily passenger-train.

The old route passes within 40 metres over the tunnel's exit.
