Telecom's first set of financial results after its split with Chorus are likely to be complicated and some analysts don't know what to expect.
Telecom will release its financials for the six months to December 31 on Friday.
During the period being reported on, Telecom went through one of the biggest corporate shakeups in New Zealand history, with its network arm Chorus becoming a separate public company in November.
Analysts say the split is likely to complicate the results and makes "meaningful comparisons" with previous periods difficult. A Deutsche Bank research note said the firm was unsure how Telecom would structure its reporting and predicted it would be "very messy in terms of detail".
Forsyth Barr's Guy Hallwright believes the results will be complicated and a "halfway house" between what the market is used to and what it will see in the future. "From what I've seen the numbers are a bit all over the place from everyone."
