  Let $K$ be a complete discretely valued field with the residue field
$\kappa$. Assume that cohomological dimension of $\kappa$ is less than or equal
to $1$ (for example, $\kappa$ is an algebraically closed field or a finite
field). Let $F$ be the function field of a curve over $K$. Let $n$ be a
squarefree positive integer not divisible by char$(\kappa)$. Then for any two
degree $n$ abelian extensions, we prove that the local-global principle holds
for the associated multinorm torus with respect to discrete valuations. Let
$\mathscr{X}$ be a regular proper model of $F$ such that the reduced special
fibre $X$ is a union of regular curves with normal crossings. Suppose that
$\kappa$ is algebraically closed with $char(\kappa)\neq 2$. If the graph
associated to $\mathscr{X}$ is a tree (e.g. $F = K(t)$) then we show that the
same local-global principle holds for the multinorm torus associated to
finitely many abelian extensions where one of the extensions is quadratic and
others are of degree not divisible by $4$.
